Bug 1354117 - only dispatch view events once, and fix synced tabs button test, r?jaws Prior to this patch, both CustomizableUI itself and the PanelMultiView module tried to ensure that onViewShowing/Shown/Hiding/Hidden listeners were invoked when the relevant DOM events fired. PanelMultiView was doing this manually because CUI was only adding listeners once the corresponding widget was created. Now that the relevant views can be accessed without the corresponding widgets (via the fixed appMenu), there was no guarantee that the listeners would be attached, and this caused empty subviews. Unfortunately, if the widget *was* present, it caused events to fire more than once, which understandably broke consumers like the sync remote tabs widget, which broke the test we're fixing up here. For other views, even if they were not completely broken it at least did busy-work. This patch removes the manual event invocation, and delegates the event listener work to CUI from the PanelMultiView side. This ensures events fire, and fire only once.

Bug 1354117 - Update various other customizableui tests for photon, r?adw There are no more help/quit buttons in the panel that shows up in customize mode, and there are no more hyphenation quirks in items in the panel, so those tests have been removed. The remaining tests are updated to test the correct panels. MozReview-Commit-ID: LiUWejjZC7c
