Build status badge is out of date

Do you want to request a feature or report a bug?

README bug

What is the current behavior?

The build status badge on the README.md is referring to the "ghuntley/reactiveui" project in AppVeyor, which is reporting the build status as "unknown".

If the current behavior is a bug, please provide the steps to reproduce and if possible a minimal demo of the problem

See the repo home page

What is the expected behavior?

Presumably the build status badge should be referring to the "dotnetfoundation/reactiveui" project, which is running for PRs.

What is the motivation / use case for changing the behavior?

Radiating the status of the build is a good indicator of the status of the project to potential new contributors (and good motivation to keep the build green 😀)

Which versions of ReactiveUI, and which platform / OS are affected by this issue? Did this work in previous versions of ReativeUI? Please also test with the latest stable and development snapshot

N/A

Other information (e.g. stacktraces, related issues, suggestions how to fix)

I would submit the PR to fix it myself, but AppVeyor appears to want the internal project ID in the build status link, and I was not able to find that ID with a quick search. Someone with direct access to the AppVeyor build could probably find it faster.

Fixed in #1478 - thanks for reporting this. Small yet important contribution.
