* Add notify user id in config
* Add dao method to get provider history versions along with tests
* BUG: Provider switching did not handle case where priorities were equal. This
* adds a fix to properly cover this case along with tests
set all existing rows to have a version of 1 (also copy across values
to populate the new provider_details_history table in the upgrade
script)
in dao_update_provider_details bump the provider_details.version by 1
and then duplicate into the history table as a new row
(done manually as opposed to the decorator used in template_history
since this is only edited in this one place and the decorator is icky)
