Daniel Lee 68833fa978 dashboard: allow alerts to be saved for new/provisioned dashboards
This changes the logic for the alert validation in the extractor. Validation
is executed twice, once before attempting to save the alerts and once after
saving the dashboard while saving the alerts to the db. The first validation
will not require that the alert has a dashboard id which allows new dashboards
with alerts to be saved.

Fixes #11247
