Include owning test name in exception when zombied SyncContext is used

[lg2de]

report the name of the thread if UISynchronizationContext is invoked and pump already ended

I was not able to run the tests locally.
The CI build seems not to work for PRs :(

We are facing issues with tests failed with

### error output ###
The active test run was aborted. Reason: Test host process crashed : Unhandled exception. System.InvalidOperationException: The message pump isn't running any more.

We would like to know which test causes the problem.
What do you think @AArnott ?

Change looks good to me.

[lg2de]

Thanks for your fast response.
We have identified the failing tests with this extension. :)

Could you please create a public (non-alpha) release?

[AArnott]

Watch for 1.1.10 to push to nuget.org in the next hour.

[AArnott]

Make that 1.1.11.
