Timezone changes when all options are removed using "edit options" path

[jonnymarshall]

Describe the bug When you go to "edit options", the timecode of the poll is preserved unless you delete ALL the existing options and then begin adding new ones, at which point the timezone defaults to your current location and cannot be changed.

To Reproduce Steps to reproduce the behavior:

1. Go to an existing poll with a timezone different to your current timezone
2. Delete all the poll options
3. Add a new option
4. The new option will have changed to your current timezone and be uneditable.

Expected behavior Whether you delete some OR all of the poll options, the timezone of the poll should be preserved.
