STR: * Open Messages app; * Enter any existing conversation; * Go back to Inbox; * Enter New Message view and enter recipient and some message text; * Go back and save draft; * Observe Inbox. Expected result: user should see just saved threadless draft; Actual result: draft is saved into conversation that user visited on step 2. It seems the reason is that we don't clean ConversationView.activeThread after patch for bug 1167144. Hence there are other bad consequences of this e.g. New Message header is updated with the text of previously visited conversation in case of contact change and etc.

[Blocking Requested - why for this release]: regression Steve, can you please take a look? Thanks!

Comms triage: Functional regression from 2.2.

Sure, will take a look immediately
