Revert 55450 - Fix CheckFalseTest.CheckFails on Linux after my change to ui_test.

This makes PathService clear its cache after overriding a path.
We have many paths depending on each other, so this is necessary
to avoid inconsistencies.

Added a comment that PathService::Override should not be called
by production code.
