heal: Fix healing empty directories (#7154)

Browse source 
This commit fixes the computation of Before/After healing state
for empty directories.

Issues before the commit:
- Before state doesn't reflect the real status (no StatVol() called)
- For any MakeVol() error, healObjectDir is exited directly, which is
  wrong.
