Changes to the use statements done automatically via script
Addition of missing use statements done manually
Change-Id: Iad87245bf8082193be72f7e482f29e9f1bad11fc

otherwise.
Also rename 2 test files to avoid a PHPUnit deprecation of file name not
matching class name.

Notably: any() is the default anyway. It doesn't really make the
tests more specific or better readable when we repeat it all the
time.
