Reviewed by Darin Adler.

The correct display of navigation items in the ContentBrowser is contingent on
the ContentViewContainer's _backForwardList being up-to-date when the navigation
items are retrieved from it. However, when the main resource changes (in this case
the user refreshes the browser), calls are made to ContentViewContainer's
closeAllContentViewsOfPrototype() which may modify the _backForwardList but doesn't
necessarily notify of a change to the currentContentView since we may be still showing
the same view in case it wasn't directly related to the main resource, for instance
the console log.

We now check if the _backForwardList is changed as a result of calling
closeAllContentViewsOfPrototype() and in that case also dispatch the
CurrentContentViewDidChange event which will restore the correct state
for the back/forward buttons and navigation items of the navigation bar.

* UserInterface/ContentViewContainer.js:
(WebInspector.ContentViewContainer.prototype.closeAllContentViewsOfPrototype):
Track changes to the _backForwardList and dispatch the CurrentContentViewDidChange
event in case such changes happened.
