L{FilePath.moveTo} clears its destination's status cache, such that
calls to L{FilePath.getsize} after the call to C{moveTo} will report the

This is a separate test from C{test_moveToExistsCache} because it is
intended to cover the fact that the destination's cache is dropped;
test_moveToExistsCache doesn't cover this case because (currently) a
