request: after adding contact navigate to conversation screen

[jpage4500]

today after adding a contact you go to the contact list -- seems like other similar apps will take you to the conversation screen right away.

I know I can just click on the contact after adding but it's hard to tell who I just added since it just shows "Unknown":

It'd be better to take the user to the conversation screen:

similar to this ticket: #1075

Working out who the new contact is will also be slightly improved in the next release as a contributor set it up so that the friend request messages now are added to the chat history.

Aliases (not yet implemented) will also help, and we should probably allow setting an alias at the same time as you send a friend request.
