qt: Remove job for refreshing OpenPGP keys

* lang/qt/src/qgpgmerefreshopenpgpkeysjob.cpp,
lang/qt/src/qgpgmerefreshopenpgpkeysjob.h,
lang/qt/src/refreshopenpgpkeysjob.h: Remove.
* lang/qt/src/Makefile.am, lang/qt/src/job.cpp: Update accordingly.
* lang/qt/src/protocol.h (class Protocol): Remove pure virtual member
function refreshOpenPGPKeysJob.
* lang/qt/src/protocol_p.h (Protocol::refreshOpenPGPKeysJob): Remove.
* lang/qt/tests/run-refreshkeysjob.cpp (main): Use ReceiveKeysJob for
OpenPGP keys.

The RefreshOpenPGPKeysJob did more than it was intended to do, e.g. it
imported new keys with the email addresses of the key to be refreshed
via the configured auto-key-locate methods, but only a refresh from the
key servers is wanted. For this we can use the ReceiveKeysJob.
