SEED groups - 500 error when trying to create a new group after selecting inventory records

Double check that users can create groups after selecting properties and selecting Add/Remove from group from the actions menu, that adding a new group from that modal works. See comments: #4849

Also double check that the functionality works when an org has an AH. (I couldn't add 2 properties in the same ALI from that modal).

@kflemin -- I see you already made an issue for this. Perfect !

Here is a screenshot showing what I did -- I selected 3 properties, then clicked on the Actions menu and selected the Add to/Remove from Groups option, when in the Create new group input box, I typed a new group and clicked on the Create Group button, which generated a 500 error
