feat($compile): add support for ng-attr with camelCased attributes

SVG attributes are case sensitive and some have upper case letters in them
This change ensures that we can identify these, when being used with the `ng-attr`
directive, by encoding upper case letters with a preceding underscore.

For example to apply `ng-attr` to the `viewBox` attribute we could write
`ng-attr-view_box` - or any of the other variants: `ng:attr:view_box`,
`data-ng-attr-view_box`, etc.

fix(orderBy): do not try to call valueOf/toString on `null`

8bfeddb5d671017f4a21b8b46334ac816710b143 added changes to make relational operator work as it
normally would in JS --- unfortunately, this broke due to my failure to account for typeof null
being "object".

This refactoring attempts to convert object values to primitives still, in a fashion similar to
the SortCompare (and subsequently the ToString() algorithm) from ES, in order to account for `null`
and also simplify code to some degree.

BREAKING CHANGE:

Previously, if either value being compared in the orderBy comparator was null or undefined, the
order would not change. Now, this order behaves more like Array.prototype.sort, which by default
pushes `null` behind objects, due to `n` occurring after `[` (the first characters of their
stringified forms) in ASCII / Unicode. If `toString` is customized, or does not exist, the
behaviour is undefined.

style(testability): throw a more informative error when getting testability

The angular.getTestability method requires an element parameter to determine
which Angular application to use. Currently, if the element provided is
undefined or outside of an Angular app, the error message is 'cannot read
property get of undefined'. Improving to a more relevant error message.

function. Additionally it was mutating its arguments.
