Squirrel version(s)
v2.0.0

Description
mgr.UpdateApp() method always return null, even the ReleasesToApply list is not empty.

I found an exception was thrown here:
https://github.com/Squirrel/Squirrel.Windows/blob/develop/src/Squirrel/IUpdateManager.cs#L171

Could not load file or assembly 'Mono.Cecil, Version=0.11.2.0, Culture=neutral, PublicKeyToken=50cebf1cceb9d05e' or one of its dependencies. The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040)

Expected behavior
Return a valid ReleaseEntry

Actual behavior
Always return null

Seems that the package Mono.Cecil referenced by Squirrel.Windows need to upgrade.
