Fix exception handling in Symbian event dispatcher

The Symbian event dispatcher handles exceptions from active objects
as well as leaves. But if the active object throws while it has
something pushed on the cleanup stack, the exception must be converted
to a leave for the cleanup to happen and the cleanup stack balance to
be maintained.
