Correctly manage instance tags about pidgin-otrng

[olabini]

This is a weird one and ties in with the meta-instance tags and other related. It's a big issue and needs to be analyzed properly.

Here we see 2 accounts. 1 pidgin is logged into as testing7878 and testingdsa is logged in twice with 2 separate pidgin and profiles.

If I start an OTR conversation, I get 2 seperate otr conversations, it picks the one which was logged in the longest I guess.

When I try to select to sent a message to the other instance tag, it doesn't seem to arrive.

Hopefully this clears up some stuff at the moment.
