Don't update status for replaced resource

With I04e7ad90944c2d03ce0e59ba16af9d60d6e01222 we allowed
update of previously-existing resource if replacement
creation has failed during last update. However, we force
update the status of the existing resource to 'COMPLETE'.
Therefore, in the next update if properties/type has not
changed for the resource it won't try to update/replace
the previously existing resource resulting in false positive
of stack updated successfully.

Task: 42194
