Upstream MR: https://codereview.qt-project.org/c/qt/qtbase/+/676173

I found and fixed a bug (likely a regression in the new code): When CN_prefill or EMAIL_prefill is configured as true and no fixed CN or EMAIL is configured then Kleopatra should prefill Name and Email with values taken from CONFIGDIR/emaildefaults (used by KDE apps on Linux), from the Windows user or from the EMAIL environment variable. This didn't work anymore.

Notes (probably as intended):

• [$i]mmutable does not work for CN or EMAIL

This probably can only be tested with signed releases?

I don't see how this could happen unless you have canceled an export. In this case Kleopatra saved an empty path as last location and then on the next export Kleopatra proposed Documents. The latest changes prevent Kleopatra from saving an empty path as last location and they ensure that Kleopatra immediately writes [Export]LastDirectory to disk.
