Jay Pipes 419cd6a8bc fix connection context manager in rc cache
This patch changes the context manager call in the _refresh_from_db()
method from this:

with ctx.session.connection() as conn:

to this:

with db_api.api_context_manager.reader.connection.using(ctx):

This is necessary to prevent errors about using a closed connection that
surfaced when writing a functional test case that tested that deleting a
custom resource class when inventory is associated with that custom
resource class.
