Delete space and PHPUnit tests pass!

A stray space in the API PHP file made whatever test came first fail. So
fix it and restore the first test.  (The other fails because Jenkins CI
doesn't have an Admin account, I left it deleted for now.)

Also remove empty setUp, and rename functions checkXxx instead of
assertXxx.
