Merge branch 'change_owner' into 'master'

Change owner on domain module changes on mail domain, sites and dns too

It's related to #97 merge request
Instead of displaying a warning about owner must be changed on mail and domain too, change it everywhere.

I have fixed some records which were not changed owner when changing mail domain's owner or web site's owner.

If you agree, I'm thinking in disable client selector on mail, domain and dns when domain module is enabled.
