Reports for geopackages which are not in latest version of the project

[jozef-budac]

Currently, reporting tool uses only geopackages in the latest version of the project. If for example some geopackage was removed in previous versions, changes in it are not mentioned in the report or in the warning message during processing. It would be nicer, if this tools can process changes also in the geopackages, which were present in previous versions of the project.
