Fail to get test function name with `test() async throws`

[ytyubox]

Hi, Thank you a lot for having this project; I love it.

I found an ERROR when using verify()

With the following test update, you can see the file name become *.ERROR.*

The approved file name is ApprovalTests_SwiftTests/Namer/NamerTests.ERROR.story1.approved.md

I would love to contribute, but I am confused about why check the process for the test function name. There is a way to inject function seamlessly, just like file and line.

Thank you! This is important, now that we can have async tests.

Hi @jonreid, could you take a look at the PR? #17

[babbage]

This is an important PR for me. Without this PR, all async tests in a test class generate the same filename of [TestClassName].ERROR.approved.txt so different tests are trying to verify against the same source. This obviously doesn't work.

Seems like a straightforward and it would be good to see it merged. :)
