Default track change cause deployment failure when using charmstore compat API

[Arif Ali]

We have an environment we have a fixed versioning of charms being deployed from the original charm-store.

As an example the following charms worked on 27th July at 11:34 UTC

cs:aodh-48
cs:cinder-310
cs:glance-305
cs:neutron-api-294
cs:gnocchi-46
cs:heat-283
cs:openstack-dashboard-313
cs:vault-46

We have since tried deployment of these charms and have unable to be able to do this, wand we get a similar message as the one below for each of them

ERROR cannot deploy bundle: cs:aodh-48 resource "policyd-override": bad metadata: resource missing filename

The default track was changed on the 28th July [1], and could potentially be the cause of this happening
