User Accept/Decline invitation access denied

OK. Further investigation reveals ginvite is using a built-in access check in the group module. That check in Drupal\group\AccessGroupInstalledContentAccessCheck->access() requires a 'group' parameter be passed or else it fails the condition !$parameters->has('group') and returns AccessResult:neutral(). As currently constructed only group_relationship parameter is found. Adding the group id to the route appears to pass enough information to the group access check to pass.

This patch adjusts the routing and edits the My Invitations view which generates operation links.

Patch #5 should fix the my_invitations view to correctly create the routes.

I decided to keep routes as they are right now, because some developers could alter they views and will miss these changes.
I just add additional check that plugin exist in our custom access check.

This issue also appeared in the 2.x branch in release 2.2 and makes it so users cannot accept invitations.

As far as I can tell, it's just a one line change to fix it.

Fixed, I will tag a new release
