Expected behavior:
When filling out the new group form, after filling out the name of the new group hitting <Enter> submits the form and the group is created.

Actual behavior: The form disappears, the page reloads, but no group is created.
Steps to reproduce:

1. login with an account that can create groups
2. navigate to the groups page
3. hit 'create'
4. enter a name for the group
5. hit the <Enter> key
6. observe the page reloading, but your new group doesn't exist

Note: test with a name of an existing group as well. It should behave same as Create button.
