After failed evacuation the recovered source compute tries to delete
the instance

Bug description:
Description
===========
In case of a failed evacuation attempt the status of the migration is
'accepted' instead of 'failed' so when source compute is recovered the compute
manager tries to delete the instance from the source host. However a secondary
fault prevents deleting the allocation in placement so the actual deletion of
the instance fails as well.
Steps to reproduce
==================
The following functional test reproduces the bug:
https://review.openstack.org/#/c/498482/
What it does: initiate evacuation when no valid host is available and
evacuation fails, but nova manager still tries to delete the instance.
