Fix poll display on delegation settings change

[bastianjoel]

resolves #3685

[Elblinator]

The polls are still not loaded correctly => no change in behaviour

having any poll in the autopilot (e.g. a running poll) results in several Errors being thrown in the console

base-repository.ts:396 ERROR 
TypeError: Cannot read properties of undefined (reading 'length')
    at AssignmentPollVoteComponent_ng_template_1_ng_container_1_ng_container_1_div_3_div_2_b_2_Template (base-poll-vote.component.html:67:29)

or a different example

The Error message seems to be not related to this issue. I just got the same Error while checking out main
I'll investigate the Error further and create new Issues

Could you approve in that case?
