Restructure the saving of the filter and string values in the localStorage.


Check if there is a reason, why using this url for:

• showAllCollections
  `/finc-select/metadata-collections?filters=mdSource.${sourceId},selected.yes,selected.no,permitted.yes,permitted.no,freeContent.undetermined,freeContent.no,freeContent.yes&query=`,
  can we just use instead: `/finc-select/metadata-collections?filters=mdSource.${sourceId}` ?

• showSelectedCollections
  `/finc-select/metadata-collections?filters=mdSource.${sourceId},selected.yes,permitted.yes,permitted.no,freeContent.undetermined,freeContent.no,freeContent.yes&query=`,
  can we just use instead: `/finc-select/metadata-collections?filters=mdSource.${sourceId},selected.yes`
