qml-core-test::WebView_scriptMainWorld is flaky

[Olivier Tilloy]

When running unit tests on trunk on my desktop, I’m regularly seeing the following test failure:

2: PASS : qml-core-test::WebView_scriptMainWorld::initTestCase()

It doesn’t happen all the time, but at least 50% of my test runs. I’ve seen this failure happen for as long as I can remember, it’s not a recent regression.

I was able to repro it on my desktop.

This bug is blocked on bug #1399218.

[Chris Coulson (chrisccoulson)]

The issue wit this is that the scripts are loaded asynchronously. I'm going to fix this by providing an API that allows us to block the test until scripts are fully loaded
