Experimental app list: Remove page indicator.

Experimental app list: Remove page indicator.

This is a partial revert of commit 6c4617f (r282586), "Experimental app
list: Added a current page indicator to the launcher.".

Latest mocks indicate the selected page by changing its icon to blue,
rather than having a blue line above the icon. The reason we are
removing this now is for spacing reasons -- we need to move the grey
separator line up by 1px but the blue line can't be moved up unless we
shrink the contents view.

Sorry, Kendra, we're removing your page indicator. But the work you did on
hooking ContentsSwitcherView as a PaginationModelObserver lives on!

I think you can remove this too?
