fix: Tolerate missing status fields on veganism.social (#911)

veganism.social is doing something weird that injects statuses into the
user's timeline that are missing the fields that are normally present on
authenticated statuses.

So far I've noticed:

- `reblogged`
- `favourited`
- `bookmarked`

on the top level `Status` are missing, and if the status contains a poll
the `voted` field is also missing.

Cover up this breakage by setting defaults for these fields.
