Add check of installed libraries

• Remove mvd from list of folders to delete when testing the installed version (folder removed from repo)
• Run the installation check both before and after removing the source folder
• Also try to load all libraries when checking the installed version

=> Expected to fail until some solution for #3577 is found, for example in new variants/versions of !2057 (merged)
