over excessive validation of assessment addresses
Description
fetchAssessmentData does always check whether the assessment is valid, which will be true in almost all cases, because the address comes from parsed events
Expected Behavior
it should only check whether the assessment is valid, when the assessmentView is loaded directly and the address is fetched from the url
Possible Solution
have a dedicated initialization procedure which after completion, triggers the necessary fetching. Or have fetching be conditional on an init-field
