(reported by Ola W. on mattermost)

Students seem to use the input field for new group creation as search box followed by hitting the enter-key.
This causes new student groups to be created by accident.

Improvements:

• add search box to filter on available student groups for joining
• enter key should not perform action to create student group
• make student group creation a two-step action with dialog
