Reactiveui: [BUG] VS 2019 Android WireUpControls throws exception

[danielvistisen]

Describe the bug
WireUpControls for android throws exception.

https://github.com/reactiveui/ReactiveUI/blob/eb53eee4bd1865b3a226ec468c0a344620349bee/src/ReactiveUI/Platforms/android/ControlFetcherMixin.cs

Line 38 gets the wrong assembly. Causes line 39 First() to throw an exception. No matching element.

In VS 2017 it gets the right assembly.

I have tested this on two machines.

Steps To Reproduce

1. Create new Android project.
2. Install latest ReactiveUI from nuget
3. Add this.WireUpControls() in MainActivity OnCreate

Expected behavior
No exception thrown

Environment

• OS: Windows 10
• Device: Tested on Andorid emulator and Oneplus 5T
• Visual studio 2019

Seems Visual Studio "fixed" this and it broke the way we were loading assemblies.

In case others run into this and want to use VS2019 before this gets fixed:
For a temp workaround I copied the class to my android project. Replaced line 38 with:
var assm = Assembly.GetExecutingAssembly();

Also renamed WireUpControls to WireUpControlsLocal and changed code to call this method instead to avoid ambiguous methods.
