DB: Add CollabTopicLocalReceive and CollabRecipLocalReceive tables

I was going to link the matching Accept tables to them, but then switched to
the Invite-Accept-Grant model and going to implement it in the next patches. So
I'm committing these new tables just in case I decide to revert to the current
model.
