* FEATURE: Do not delete invite if link was copied
* FIX: Show error to user if invite redeeming fails
The error was only displayed to console.
* UX: Better placement of bulk buttons
Destroy all expired invites should be on the expired tab, not pending.
* FIX: Ensure invited_groups is unique per invite and group
* FIX: Do not refresh topic list if title unchanged
* FIX: Do not close modal on enter
This intereferes with the group and topic chooser.
Wrapping everything in a form disables this behavior.
* FIX: Move link and email options outside advanced section
* FIX: Do not close modal if saving a link invite
User may still want to copy the link.
This reduces chances of errors where consumers of strings mutate inputs
and reduces memory usage of the app.
Test suite passes now, but there may be some stuff left, so we will run
a few sites on a branch prior to merging
