Fix "Unable to restart VM after applying CETS preset"

[arcusfelis]

This PR addresses "MIM-2071 Unable to restart VM after applying CETS preset"

Proposed changes include:

• Disable strict check that mnesia is running for mod_register and ejabberd_auth_anon (they are still not supported by CETS though).
• Configure mod_stream_management with the proper backend in the templates.
