git-p4: small fix for locked-file-move-test

The test for handling of failure when trying to move a file
that is locked by another client was not quite correct - it
failed early on because the target file in the move already
existed.

The test now fails because git-p4 does not properly detect
that p4 has rejected the move, and instead just crashes. At
present, git-p4 has no support for detecting that a file
has been locked and reporting it to the user, so this is
the expected outcome.
