blank saves do not have the type metadata for the blocks that are spoofed, nor do they have all blocks spoofed.
I suspect things might get more difficult as more value-blocks are identified, which would throw a wrench into things. We'll figure that out at that time :)
Add a test to ensure that the blank save can be created correctly
Closes#2644
* Rewrite tests with XUnit and .Net Core
* Add better "because" message
* Skipping test that was not ready & convert the fact to a theory
* Tweak casing
* Convert select date tests to theories
* Make the GetStringList load lock safer
