[...] add original watchkit app/extension test coverage

[brody2consult]

test cases by @l3ender for WatchKit2 in apache#56, adapted to test the original WatchKit support instead

with some changes marked "ORIGINAL" and "TBD ???" to indicate what was changed for WatchKit vs WatchKit2

I think we should add these test cases to apache/cordova-node-xcode before we add WatchKit2 support.

When I tried mutation testing with Stryker, as proposed in apache#61, these test cases seemed to kill a few more possible mutants and increase the code coverage a little more. For comparison:

• https://chrisbrody.com/node-xcode-mutation/index.html - Stryker mutation report without these changes
• https://chrisbrody.com/node-xcode-mutation-with-original-watchkit-test-coverage/index.html - Stryker mutation report with these proposed test cases

TEST TODO:

• I think this test coverage is still not 100% complete. From Stryker mutation testing (see [rfc] mutation testing using Stryker Mutator apache/cordova-node-xcode#61) I discovered that the following possible mutations (possible code changes) related to the WatchKit would still not be detected by these test cases:
