Update cordova-osx

[alalamav]

• Updates cordova-osx to v6.0.0.
  • Unlike cordova-ios, cordova-osx still uses WebView, so local storage migration is not necessary.
• Version-controls macOS plugin configuration files as a workround for a failure to restore plugins from package.json.
  • Reproduced this issue in a minimal macOS project; manually adding plugins results in the expected configuration.
  • I'm not yet sure if this is an issue with cordova-osx, cordova-cli or one of its dependencies, i.e. cordova-common, cordova-lib (note that all these had breaking updates).
• Minor iOS compatibility fixes.

I'm not sure I understand. Do you get different configuration files when you add the plugins from the package.json? Adding manually works, but automatically gets you an error?

Perhaps we need a comment somewhere explaining how to revert when things are working.

Could you add a comment explaining why this was added and what needs to be done to clean up?

[alalamav]

Wanted to get your thoughts about where to add the comment. I was thinking of adding to package.json for visibility.

package.json sounds good to me

Do you get different configuration files when you add the plugins from the package.json?

Yes, it seems like instead of adding all plugins to the config files (cordova_plugins.js, osx.json, config.xml), only the last installed plugin overrides the config.

Adding manually works, but automatically gets you an error?

Restoring from package.json (automatically) fails. The committed config files result from manually removing and adding each plugin.
