Trigger Factory - Inconsistent Returns

[AlexCuse]

If no trigger matching configured name is found an error is logged, nil trigger is returned and handled by the SDK.

If an error is encountered when intiializing a custom trigger, an error is logged before panicking. I think in case of these errors it makes sense to force returning nil (even if the function returned a trigger and an error) and let the SDK handle it like it would any other nil trigger situation.
