Bug 1442694 - Fix failures due to removing selected tab r=Gijs This adds test which reproduce the failure as well as the fix. Essentially, if we hit the edited case in SessionStore with `tab` equal to `tabbrowser.tabs[t]`, we remove the tab and then try to pin it, which obviously blows up. Note: the additional method in SessionStore.jsm was largely to get around complexity requirements inside restoreWindow. Cleaner solutions welcome.
