Add explicit error for destination without simulator

[rocketlobster]

Checklist

• I've run bundle exec rspec from the root directory to see all new and existing tests pass
• I've followed the fastlane code style and run bundle exec rubocop -a to ensure the code style is valid
• I see several green ci/circleci builds in the "All checks have passed" section of my PR (connect CircleCI to GitHub if not)
• I've read the Contribution Guidelines
• I've updated the documentation if necessary.
• I've added or updated relevant unit tests.

Motivation and Context

😭 Before:
When configuring a new target with UI tests to setup Fastlane Snapshot, it's easy to get fooled and add an unwanted "Mac" destination.
In this case, when launching fastlane snapshot, user receives a cryptic error:
Error running screenshots command - latest_simulator_version_for_device: undefined method `os_version' for nil:NilClass .

👍 After:
With this change, if no simulator is found for a given device, display a pretty error to show for which device, so that users can quickly understand that the destination target is wrong.
