Scenario
Given: the SSO on 2FA feature is installed on an existing installation.
And: I run the migration that creates the Gateway projection schema
And: I configure one of the institutions to use SSO on 2FA
Then: the gateway institution configuration should be updated to reflect the configuration value

Problem
However: the projector does not create the projection row if it does not exist yet.

Solution
The best solution would be to run an event replay. Ensuring all institutions are present in the GW institution configuration projection.
The next best solution is to make the projector aware of the possibility, an institution is not yet projected. And let it create the row on the fly.
