Description of the changes in your PR

To save location of import/export, I add a new preference key for import_export_path and save this preference on result of file chooser activity and send it on intent of file chooser on later tries.

So as a user, If a export data on folder foo, when I want to import this data, file chooser show foo as start path.

Fixes the following issue(s)

• Fixes Store backup location #6039

Codewise looks fine to me now.

I don't know how to rebase #5415 on top of this... I think that storing the last used path would require some more work in saf.
