Motivation
Currently the elections held via SecurePoll cannot be modified once they begin. But often some minor changes to the elections need to be made after the election has started - such as when election admins withdraw or need to be replaced. This task is to allow some of the configuration settings of an election to be changed after the start of the election.
We won't be allowing modifying everything to risk any untoward consequences. Maybe we can start with:
- Allowing changes to election admins
- Allowing changes to the Return-to-URL field
