Group members should not receive group membership request notifications

[Richard Schütz]

Notifications about new group membership requests are also sent to normal group members, which leads to a lot of useless emails. Only group administrators should receive this type of notification.

This behaviour was first observed after upgrading to Mahara 16.10.0, thus seems to be a regression.

[Richard Schütz (rschuetz)]

This seems to be caused by the proposed fix for bug #1461331. Reverting the commit fixes the issue.

I've made a patch so that we can indicate exactly which users are to get the email by supplying user ids to GroupMessage to fine grain who gets the messages.

[Robert Lyon (robertl-9)]

Normally we can just pass in the roles but here we are wanting to translate the emails individually to the preferred language for the admin of the group.
In this way if a user viewing the site in Spanish can request an invite to a group where one group admin's preferred language is German and another group admin's preferred language is Spanish and they both get their emails in their preferred language.

Bug 1637287: Restrict the group membership request to admins only

Since we changed the message activity from 'maharamessage' to
'groupmessage' we need to restrict the users getting the message to
the admins.

Also update the group_invite_user() message to be a groupmessage as well
