At this moment it was possible to enter emails like:
mailto:info@example.com. This was causing some issue in the frontend,
since those links became html mailto: links.

Fixes: #3516

Remove unnecessary projects order on User#show

500 error was occured in the following steps:

1. user1 creates new team "team1".
2. Assign team1 to project1.
3. Sign in as admin. This admin is not a member of team1.
4. Open project1 team setting page (/project1/team).
5. Click "team1" link in "Assigned teams" area.
6. 500 error.

Fixed this issue.

“Can create groups” and “Can create teams” had hardcoded defaults to
`true`. Sometimes it is desirable to prohibit these for newly created
users by default.
