Just wrote a test that reproduces the behaviour described here.  It
looks like the code correctly tidies up the inotify watches for the
moved subdirectory, but doesn't remove the moved files from the index.

  version version: 144
  version ubuntu: 20150528.1
  version device: 20150210

  1. Add media, in this case /home/phablet/Music/CD1
  2. Rename media to /home/phablet/Music/Chopin - Noctures 1/
