* Revert "Revert #10957 (rubocop-rails) which is incompatible with CodeClimate (#10965)"

This reverts commit 121d19d7.

* Disable Rails/HelperInstanceVariable

* Fix emoji picker being always displayed

* Remove duplicate content with other pull-requests

* Scroll to compose form when focus

* Get rid of constructor

* Remove skip_session! as it is not supported in Rails 5

* Minor cleanup in StreamEntriesController

* Remove redundant mark_cacheable! calls

Fixes #10945

* Do not misattribute inlined boosts if `attributedTo` isn't present

Fixes #10950

* Fix tests

* Fix poll API not requiring authentication on non-public polls

That API does not reveal the content of the status, i.e. the question
itself, nor who the author is, nor which status it belongs to, but it
does reveal the poll options and how many answers they got

Fix #10959

* Add test

And change some word.
