MDL-75880 phpunit: fix all @coversDefaultClass missing @covers

Because @coversDefaultClass doesn't indicate any coverage (it's
just an alias to avoid having to write the class name in @covers),
this commit fixes all the files that were using that annotation
and missing any @covers.

Basically, replacing one by the other and done.
