Upgrade ios-simple to use Appium 1.6.0

[dpgraham]

-Replaced elementByIosUIAutomation call with elementByAccessibilityId because we use the appium-xcui-test-driver which doesn't support UIAutomation
-Upgraded appium-version in desiredCapabilities config file (caps.js) to version 1.6

@dpgraham it looks like your git user isn't set up with the same e-mail as your github user, mind fixing that and re-committing? code LGTM

[imurchie]

Moving forward can you put the language in the title, too (ios-simple exists in a number of the languages in this repo)? Looks good, otherwise!

[jlipps]

one comment then LGTM

[jlipps]

we probably don't want to commit visual studio code files. my suggestion would be to add this to your global .gitignore

[jlipps]

Oh, @dpgraham looks like your machine's github user is still not set up to use the same one as @dpgraham on github

[jlipps]

@dpgraham mind repushing as your GH user, and cleaning up the launch.json file? then we can merge this.

I've pushed to it with my new credentials.

@dpgraham it's still not working; somehow your old user is also attached on some of these commits. it might be better to just squash them so it all gets rewritten as your new user, and force-push to the PR branch?

[dpgraham]

Done. I squashed them together and reworded the commit message. Should be good now.
