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.

This commit mostly reverts the commits
e12861f18c6b431b40bfa78eb6f1d149690a5fcd
c64a8daf507a2216611861a12f312466b0bae8b2

The changes are source- and binary-compatible to the last release.
