Fixed bug where deleteAll tried to delete same id multiple times.

Ensure find done in deleteAll only returns distinct ids. A wacky
combination of association and conditions can sometimes generate
multiple rows per id.

Fixed bug where deleteAll tried to delete same id multiple times.

This makes using mocks much easier with event listeners as they don't
need to provide a returnValue for implementedEvents.

Cast implemented events to an array when detaching listeners.

This makes it much simpler to work with mocks, and avoids warnings caused by developer error.
Append / to the start/end of the mapResources prefix.

This makes the method easier to use and less error prone.

Fixes #2431
Baked test methods are marked incomplete.

Previously empty (and "passing") test methods now include PHPunit's `markTestIncomplete()` to better reflect the truth of the resulting file: The test methods are stubbed out, but are not yet complete and passing.

It is much easier when _running_ tests to locate incomplete test methods.

Fixes 2437.
