Lower PropertyChange.Fody version to fix runtime failure

[jjw24]

Dev build runtime start up failure when %userprofile%\.nuget\packages\propertychanged.fody folder is deleted:
"
Description: A .NET Core application failed.
Application: Flow.Launcher.exe
Path: C:\Users\Blah\AppData\Local\Flow\app-1.0.0\Flow.Launcher.exe
Message: Error:
An assembly specified in the application dependencies manifest (Flow.Launcher.deps.json) was not found:
package: 'PropertyChanged.Fody', version: '3.2.8'
path: 'lib/netstandard1.0/PropertyChanged.dll'
"

Reduce the PropertyChange.Fody version.

Just putting out a temporary prerelease so it's not broken, while this is under review.

@jjw24 do we actually use PropertyChanged.Fody?

I don't see any uses of INotifyPropertyChanged or the AddINotifyPropertyChangedInterface Attribute anywhere, except in Flow.Launcher.Plugin/BaseModel.cs... but this file is modified because of JetBrains.Annotations.

I have looked into the compiled dll with and without PropertyChanged.Fody and cannot notice any difference.

That said, I have been trying the various versions of PropertyChanged.Fody and noticed that version 2.5.13 is the latest version that does not cause runtime errors...

[jjw24]

@JohnTheGr8 happy to remove if not used, there are bits of code that are left overs which I am keen to get rid off. I will have a play without PropertyChanged.Fody and put in a commit if via to do so.

the package has been downgraded to 2.5.13 in #35
