Always fall back to root scroll layer for otherwise ignored scrolls

Rather than special case when the scrolling layer should default to the root
layer upon an ignored ScrollBegin, always set it to the root layer.  This
avoids platform differences and eliminates corner case logic for setting
the currently scrolling layer.

Delay loading the NTP after sign in until MergeSession has been performed in
the content area.

Also fixes a bug where the account reconcilor would run concurrent
MergeSessions on startup if there are multiple accounts connected to the
profile.  This led to a race condition that could mess up the gaia cookie.

Added more tests to  GoogleAutoLoginHelper.
