[ci] Run Debug Test first and Clean between runs (#9380)

Context: #9006

There are some odd build issue were Release artifacts were present in
the Debug configuration build of
`tests/Mono.Android-Tests/Runtime-Microsoft.Android.Sdk/Mono.Android.NET-Tests.csproj`.

This only happens in this test project.

I suspect it is because we are overriding `$(Configuration)` in the
project, but not always since we are also building in a `Release`
environment.  Both the top level `Configuration.props` is using
`$(Configuration)` as well as the test project, but the test project
gets a value of `Debug` from the build yaml.  I think it is confusing
things, but I have not been able to track it down.

Lets try to clean up the `Mono.Android.NET-Tests.csproj` test project
after it has been built and run, to make sure any old outputs are not
there.

Also try running the `Debug` test first, so that it's running in a
clean environment.
