[AI Infra] Update logic for getConnectorById

[qn895]

Summary

This PR updates logic for how connector is fetched: to not throw error if system action. In doing so, this also clarifies at which stage an error happens. I.e. if there's a problem with fetching the connectors, if the connector does not exist, or if the action type is incompatible.

I lack context on what we're trying to address here, but fetching all connectors when we only need to access one feels wrong to me?
