tests: add a test demonstrate that 'revert -i' ignores nonexistent patterns

As described in issue5789, when revert is called through:

  hg revert -i <some file that does not exist>

we'd expect the command to abort early. Currently, it just warns about
missing file but prompt about files unrelated to user arguments.
