Loading Solutions / Module assemblies from json should accept optional modules db

At the moment loading a solution from a json file recreates the required database from disk increasing memory consumption considerably if multiple solutions from the same db are compared (some databases can be >> 100 MB of RAM so loading a few solutions from json can easily lead to >> 1GB of RAM usage).

Maybe also combinable with the integration of cobra-io for getting tasks, assets, and databases by name.
