lock: Set ticket lock on ticket-view

Since the automatic lock was being acquired but not passed to the autoLock
system, the automatically acquired lock was not being release on away
navigation.

This patch addresses the issue by passing the automatically acquired lock id
to the autoLock system on ticket-view page load and change the ::Init()
method so that the lock id is not cleared with the ::Init() method is called
by the page load.
