Second bustage fix for bug 495020. Fix a couple of issues, one related to bug 495020 and one related to bug 545221. 1. In test-display-message-with-folder-modes.js, the change in behaviour in bug 495020 means that the message is in the view at the time it is attempted to be displayed, thus the folder the message is in isn't expanded. Fix that by selecting a different folder before changing modes. 2. In messageInjection.js, make sure we use createSubfolder for the inbox and not addSubfolder. This causes an OnItemAdded notification, which the folder tree view gets to know that it needs to update itself. Without the fix, the inbox isn't displayed unless the folder mode is rebuilt. (This used to work earlier because the default used to be smart folders, and we used to switch to all folders after creating the inbox. Bug 545221 changed that.)
