Subject: [PATCH] Run wilde on iOS emulator during electron tests

Summary:
Before running the test suite, build wilde and run it on a local emulator.

This takes about 15 mins on a lego-mac with a warm cache.
It's probably worth splitting out the normal unit tests into a separate job, so we get quicker feedback on them. I'll do that in a separate diff.

Lets run this for a while, and see how it goes, I'm wondering if it might get flaky because it will be building the master version of wilde, so potentially could be broken a lot, though it's passed evry time I've tried it so far.

If it's reliable, we can run the same thing with loads of other apps in parallel.
