Reverting any single of the scripts from standard recommendation pool
shows "Standard" selection as selected which is wrong. This commit fixes
it, refactors selection handling in a separate class and it also adds
missing tests. It removes UserSelection.totalSelected propertty in favor of using
UserSelection.selectedScripts.length to provide unified way of accessing
the information.
- refactor array equality check and add tests
- remove OperatingSystem.Unknown causing extra logic, return undefined instead
- refactor enum validation to share same logic
- refactor scripting language factories to share same logic
- refactor too many args in runCodeAsync
- refactor ScriptCode constructor to reduce complexity
- fix writing useless write to member object since another property write always override it
