Fix: Update field trigger unit test to validate on state type. (#3982)

## Summary
Field triggers apply to the state type, since they are applied after
`PrepareState`. They do not apply on the input config schema. This was
not a problem until now because both state and config were the same.

That's not the case, however, for secret scopes. Created a separate PR
because of the prompt in:
#3886 (comment)
