MDL-44065 Course: _add_instance exception leads to inconsistent db

If an exception occurs during a module's _add_instance function, this
results in a course_modules entry with instance=0. The system already
handled returning false to this function, but did not handle
exceptions.
MDL-43930 assign: Do not log when user is logged in as someone else.

I do not agree with this behaviour - but this makes it consistent with other modules.

The previous (slightly whacky) way that we were doing this in previous
versions is no longer supported (and was arguably only supported by being
buggy).

The correct way of doing this is to use a trigger.
MDL-43713 behat: improve multi-select support

This patch implements:

1) Normalization of options. Before the patch options
in a select were being returned as "op1 op2 op3" by selenium
and "op1 op2 op3" by goutte. With the patch, those lists
are always returned like "op1, op2, op3". If real commas are
needed when handling multiple selects they should
be escaped with backslash in feature files.

2) Support for selecting multiple options. Before the patch
only one option was selected and a new selection was cleaning the
previous one. With the patch it's possible to pass "op1, op2" in
these steps:
  - I fill the moodle form with (table)
  - I select "OPTION_STRING" from "SELECT_STRING"

3) Ability to match multiple options in this steps. Before the
patch matching of multiple was really random, now every every
passed option ("opt1, opt2") is individually verified. It applies
to these 2 steps:
  - the "ELEMENT" select box should contain "OPTIONS"
  - the "ELEMENT" select box should not contain "OPTIONS"

4) Two new steps able to verify if a form have some options selected or no:
  - the "ELEMENT" select box should contain "OPTIONS" selected
  - the "ELEMENT" select box should contain "OPTIONS" not selected

5) Change get_value from xpath search to Mink's getValue() that is immediate
(does not need form submission) and works for all browsers but Safari, that
fails because of the extra ->click() issued.

Note all the changes 1-4 only affect to multi-select fields. Single
selects should continue working 100% the same.

The change 5) causes Safari to fail. The problem has been traced down to
the extra ->click() present there. Anyway there are not test cases
requiring that "immediate" evaluation right now. Only the special feature
file attached verifies it.
MDL-43738 behat: Functional tests for fields management

We are cheating with this .feature file as this
is not a behaviour and we are just testing the
framework, but in this case I think that everybody
will agree on the need of doing it, as every browser
behaves differently and minor changes in the getters
and setters can easily end up breaking the behaviours.

All credit goes to Eloy Lafuente (stronk7).
MDL-43738 behat: Normalization and major refactoring of getters and setters

Every single step that sets or gets a value from a field
has been updated to follow the same behaviour both when
using it through a single step or through generic steps
like "I fill the moodle form with:", to resume all the
changes:
- Created a behat_form_group to re-guess the field type
  and act appropriately setting and getting it's value
- Normalize all getters and setters to use behat_form_field
  children
- Complete behat_form_checkbox to trigger the appropiate JS
  event needed to perform some JS scripts that are listening
- Refactor MDL-43713 multi-select changes and remove
  the two new steps introduced there as that behaviour can
  be managed from the generic getter
- Added a new step definition to check a capability permission
  as we changed the way radio buttons gets it's value
MDL-43738 behat: Updating steps definitions and deprecating methods
MDL-43738 behat: Updating features files

The following used steps were replaced by the ones
added in this issue:
- I fill the moodle form with
- I fill in with
- I select from
- I select radio button
- I check
- I uncheck
- the field should match

Also removing test for deprecated steps:
- the ASD checkbox should be checked
- the ASD checkbox should not be checked
MDL-43738 behat: More info about how to get/set fields
MDL-43738 behat: Refactoring the field type guesser

The previous behaviour delegates the responsability
of overwriting the 3 public methods to the child
classes, now the field type or moodleform field is
guessed earlier in the execution flow.

Other changes introduced here:
- Fix wrong moodleform detection when there is a form
  in the page but the field we are dealing with is
  not inside it.
- Updating the last week feature files to these new
  step definitions.
- Some coding style changes.

The affected code areas are not supposed to be used in any add-ons,
the backwards compatibility should not be a concern for us.
