Add fallback for missing version information in database (#1175) 

### Describe what your pull request does and which issue you’re targeting
As described in #1174 the app crashes if a bogus version (empty string) is stored in the database. In case of an empty version information in the database, the fallback should be to gracefully treat this as a version 0. This way every check for a "version greater than" fails.

After all the version information will be updated from the server anyways.
