Overcommit settings:

PreCommit:
  RuboCop:
    enabled: true

Also tried to disable symlink but still not working

PreCommit:
  BrokenSymlinks:
    enabled: false
  RuboCop:
    enabled: true

Apparently it works just fine when running overcommit -r but still not working when trying to commit

Looks like a duplicate of #791. Would welcome a contribution to fix.
