Verification of what happens when trying to upgrade from a erroneous version

[jthambly]

With the following versions, we cannot generate the source to determine which files should be removed.

1.10.0.Final
1.11.0.Final
1.11.1.Final

Although we might not be able to use the above versions for testing, automated testing should also test for instances where it needs to proceed with the backup method of updating project files.

This will not be done as apart of the GitHub Action work, instead it will be associated with issue #13

For this to be achieved we will need a way to verify the filesystem post update.
