FEATURE: Staff only poll results (#7984)
* FEATURE: Staff only poll results

These changes allow only staff to see the results of a poll.

Non-staff users will be shown a screen like this:

The "Votes are public" message has been removed from the info section,
and the button to show the votes has been replaced with a message
stating the results will only be shown to staff.

* Update PR based on feedback

* Update plugins/poll/app/models/poll.rb

make sure we return a boolean
