Avoid flash when aborting CTA.

Sometimes there is a visual glitch when ChromeTabbedActivity finishes
itself after starting another activity. For example the associated bug
documents a case where there is a momentary flash during custom tab
redirection.

The glitch is caused by abortLaunch() calling overridePendingTransition()
to do the following:

1. Disable exit animation on CTA window.

2. Force enter animation of the next window to be 'activity_open_enter'.

Both of those arguments were chosen without much experimentation, and
together they cause a flash because initial state of 'activity_open_enter'
animation is a transparent window, and canceling exit animation on a CTA
window immediately removes it.

This CL fixes overridePendingTransition() call to do the following:

1. Use 'no_anim' for the exit animation. This causes CTA window to be
   visible for a short amount of time (should enough for the next activity
   to render its UI).

2. Disable enter animation for the incoming activity. Animating another
   window on top of still CTA window just doesn't look good.
