Remove deprecation warning for FIXTURES_PATH

FIXTURES_PATH has a bit different case than DatabaseTasks.fixtures_path,
which was added along with deprecation. A use case for FIXTURES_PATH
could be loading fixtures from a different directory just for a given
test run. The implementation is fairly simple, so leaving it as it is
won't hurt.
