Changes pref for whether last session exited cleanly from a boolean to

a string pref that enumerates the ways the session ended: normal,
result of logout/shutdown, crashed. I need this for knowing when
TabRestoreService should restore from the previous session.

BUG=150799
TEST=none, this is prep for real fix
