* [msbuild/tests] Remove car idiom from Contents.json
The car idiom is something new projects used to generate
and that actool doesn't handle anymore.
Logs were polluted by a warning: "The app icon set 'AppIcons' has an unassigned child".
* [msbuild/tests] Add tvOS extension test
We now have MyTVServicesExtension project which
comes from a simple tvOS extension template.
It is attached to MyTVApp.
The TVApp test has been updated to also build the extension.
* [msbuild/tests] Fix Action Extension version number
The action extension project now has a version number that
is matching the parent app.
Avoids warning message.
