The duplicated interface will no appeared anymore. The problem is with the "stack memory" who do weird thing with his fragments.
no more duplicated stuff after that ;)
Also, fixes crashes when entering tag and threads due to me forgetting to implement the interfaces required by the code that removes posts from timelines when blocking/muting.
Also fixes a small bug where for mentions of users from other instances, clicking on the mention would open the profile in the browser instead of in-app.
