Make test database cache lookup concurrent
has_cache() is used to dertermine if the template database already exists or
not.
When running tests accross multiple process, has_cache() wasn't aware of
databases created by other processes because it used a cache to generate the
cache...
Since the discovering discover_cached_db() time is quite reasonable (it's just
about listing file in a directory), let re-generate the cache on cache miss.
