inotify: fix issue1375, add a test.

The biggest problem was the data structure, which did not allow changing
a file into a directory or vice versa. This problem is fixed by b55d44719b47.

The walk() method also had an issue in this case:
 - we know 'path' as a directory. inotify server sleeps.
 - 'path' is deleted
 - 'path' is recreated as a file
 - the server catches up here, and see the deletion. it instantiates a scan(),
   which in its turn calls for walk(repo, path).
 - walk() then assumes that 'path' is a directory and calls os.listdir on it,
   which raises an OSError(errno.ENOTDIR)

Catch the error, and yield the file instead of the directory contents.
