qt: Emit import result when refreshing OpenPGP keys

* lang/qt/src/refreshopenpgpkeysjob.h: New.
* lang/qt/src/Makefile.am, lang/qt/src/job.cpp: Update accordingly.
* lang/qt/src/qgpgmerefreshopenpgpkeysjob.h (class
QGpgMERefreshOpenPGPKeysJob): Derive from RefreshOpenPGPKeysJob with
result ImportResult. Remove unused start overload.
* lang/qt/src/qgpgmerefreshopenpgpkeysjob.cpp (locate_external_keys):
Ignore result of KeyListJob. Return import result.
(receive_keys): Return import result.
(refresh_keys): Merge the two import results and return the result.
* lang/qt/src/protocol.h (class Protocol): Add pure virtual member
function refreshOpenPGPKeysJob.
* lang/qt/src/protocol_p.h (Protocol::refreshKeysJob): Return nullptr
for OpenPGP protocol.
(Protocol::refreshOpenPGPKeysJob): New.

* lang/qt/tests/run-refreshkeysjob.cpp (main): Use appropriate job
for the protocol of the key to refresh.

This adds RefreshOpenPGPKeysJob complementing RefreshKeysJob (for S/MIME
keys). Changing the result type of RefreshKeysJob would break the ABI.
Therefore we have to introduce a new base class for the refresh job for
OpenPGP. We derive this base class from AbstractImportJob because we
want to return an import result.
