[session_shell] sessionmgr uses SessionShell

Use the SessionShell service of the session shell to forward
views of stories started by RequestStart() calling AttachView().

If a story was started by RequestStart(), and it's stopped,
then the session shell is also called with DetachView().

Use the RequestStart() method in one test case in session_shell_test.
It is not yet used anywhere else. After this is submitted, clients
can be migrated from using Start() to RequestStart(). Once Start()
is no longer used, it can be removed.
