Android: Ensure single TabWebContentsObserver per Tab

TabWebContentsObserver is TabWebContentsUserData which is created
for the first active WebContents for a given Tab, and finally
destroyed together with the Tab. There was a bug creating
multiple instances of the observer for every new active WebContents.
This left an instance for old WebContents undestroyed, and caused
a reported bug for already nulled out WebContents references
while handling an event that should not have been triggered.

This CL makes sure there will be a single TabWebContentsObserver
for Tab.
