Call finalize synchronously when app termination is requested by app fw

Call finalize synchronously when app termination is requested by app fw

Current code always calls finalize using ecore timer, so finalize codes must be called on next
event loop. However, finalize can not be worked because there is no event loop when app is
terminated by outside app terminate request. This behavior can make unintended problem.

To resolve this problem this patch makes server call finalize synchronously when app is terminated
by outside request. By this change, finalize must be called in the case.
