Suppress logged warning on calls to propsData()

[mcmilleon-will]

In our tests we often validate default data and prop values for the component under test using something like this:

componentUnderTest.data().should.deep.equal({
 // all expected data values go here
});

componentUnderTest.propsData().should.deep.equal({
 // all expected props values go here
});

We're using v4.2.0 and this works nicely for calls to data(), and it does also work when calling propsData(). However, when calling propsData(), we always get the warning:

functions returned by propsData() will not have this bound to the vue instance. Calling a propsData function that uses this will result in an error. You can access propsData functions by using the vue instance. e.g. to call a method function named propsDataFunc, call wrapper.vm.$props.propsDataFunc(). See #15');

I understand the reason for this warning message, but its muddying up my test output. Is there a way I can suppress it without muting other potential warnings from avoriaz?

There's not currently a way to hide the warnings, would you like to make a PR that adds the feature?
