[BUGFIX] YouTubeRenderer "controls" option

The "controls" parameter appended to YouTube embed URL is either set to
value provided in $options array or to default backwards-compatible
value (controls=2).

Specifically, if controls option is set to 0, the controls parameter
must be present in URL, because default value for it is 1.

Fix is applied to related unit test too.
