[TEST] Add paths to profiles to ease features select

Since the change of the [grouped features to spread ones](https://github.com/ezsystems/ezpublish-kernel/pull/889) that the feature files will be all under the same root, 

so instead of having few tags spread all over the features to select the exact ones, we can simplify with paths on the behat.yml and have a simple approach to the feature files.

PS:
the setup wizard feature might look more complicated than before but really it have more tags do identify the seveal possibilities, contemplating the future testing of the SW where it will test all installations in the same suite.
Actually I do agree that the name is kind of weird and not clean at all.

Any idea for a good name?

this will execute:
- Setup Wizard
to install
- Demo w/ Content
and on a CI configuration that has
- more than 1 DB

These might help on ideas for naming
