Fix exception due to BDM race in get_available_resource()
If we run the resource tracker periodic at the right time, we
may try to collect BDM info from a newly-created instance before
we have any BDM records for it. This patch excludes instances
that have no reported BDMs to avoid choking there. This also
adds a test which simulates an instance that is partially in
the database, but is not fully created.
