Fix and clean the tests project and add run_test_projects.yml

[charlesroddie]

• Fixes NuGet.Config, adding nuget.org as a package source. Previously only the MyGet feed was configured, causing restore failures for packages not hosted there. Also fixes the MyGet link and routes UndecodeSharpFork explicitly to Myget.
• Fixes and cleans the MediaPortal.Tests project setup so it builds and runs in visual studio.
  • Migrated from NUnit 2 to NUnit 3.
  • Removed all the checked in binaries and other extraneous artifacts, referencing properly from Nuget.
• Adds a new GitHub Actions workflow to run the tests. NB this is not tested: I believe on github you have to merge a new yml file before you can run it.
• For the failing tests, fixes most of them, deletes one which is nonsensical, and ignores the remaining ones with a comment.

Test build - CI AppVeyyor - Failed

[doskabouter]

I agree with all remarks of andrew

[doskabouter]

Can you at least revert the lines that appear as changed? Mostly first and last lines of the file. Don't exactly know what changed that makes git think it's changed, but it's distracting at the very least

private? appveyor is public: https://ci.appveyor.com/project/MediaPortal/mediaportal-1

[charlesroddie]

OK thanks. I see them now. Perhaps I clicked on the wrong link before.

Trying to fix appveyor now.

I believe when this is done you can remove these packages from MyGet as they exist on Nuget with the same versions:

CSCore 1.2.1.2
FFmpeg.Win32.Static 4.1.1.1
FFmpeg.Win64.Static 4.1.1.1
HtmlAgilityPack 1.11.46
MediaInfo.Native 21.9.1
MediaInfo.Wrapper 21.9.2
MediaInfo.Wrapper 21.9.3
MediaPortal-iMON-Display 1.1.0
MetadataExtractor 2.8.0
NAudio 1.10.0
Newtonsoft.Json 13.0.3
NUnit 3.14.0
NUnit3TestAdapter 4.6.0
SharpDX 4.2.0
SharpDX.Direct3D9 4.2.0
SharpDX.DirectInput 4.2.0
SharpDX.Mathematics 4.2.0
SharpDX.RawInput 4.2.0
SharpLibDisplay 0.3.4
SharpLibHid 1.5.1
SharpLibWin32 0.2.1
System.Management.Automation 6.1.7601.17515
System.ValueTuple 4.5.0
XmpCore 6.1.10.1

you can remove these packages from MyGet

Why? What's the point?
We can't completely stop using MyGet, so there's no point in removing anything. Especially since MyGet proxies NuGet.

We already fix Nuget:
