feat: enable not strict ios simulator versions (#422)

* feat: enable not strict ios simulator versions

Enable not strict iOS simulator versions.

Reason behind this:
- Xcode 11 do not provide older version of iOS13 except latest
- That cause variaty of iOS 13.0, 13.1, 13.2 and so on versions on different machines (it may be machine of external contributor as well)
- We need to give a chance for everyone to run those tests instead of hardcoding fixed version.

* chore: fix cases when watchTV sdk is available
