Fix accidental poll removal on status edit.

[bocops]

As detected via #166, editing a status containing a poll using editStatus() will remove the poll. This clarifies our documentation by stating that:

• poll statuses should not be edited using editStatus()
• all poll data that should not be changed during an edit via editPoll() needs to be retrieved from the existing status first.

Removes default values from two poll parameters in editPoll() to avoid an accidental change when editing.

Fixes one unrelated typo in the actual request.

The poll parameters should be refactored into a separat poll data class and the data class itself should then be placed in the *.entity.data package, as discussed in the associated issue.

[bocops]

I've now added the changes as discussed. Turns out, having two classes both named Poll is a bit problematic, though. My suggestion would be to rename the new one to PollData. @andregasser what do you think?

[andregasser]

Sure, that's fine! 👍🏻

[bocops]

@andregasser Done.

[andregasser]

Approved!
