qt,tests: Verify reason code and description of revocation
* lang/qt/tests/t-revokekey.cpp (RevokeKeyJobTest::testRevokeKeyAsync, RevokeKeyJobTest::testRevokeKeySync_noReasonDescription, RevokeKeyJobTest::testRevokeKeySync_oneLineReasonDescription, RevokeKeyJobTest::testRevokeKeySync_twoLinesReasonDescription): Call verifyReason. (class RevokeKeyJobTest): Add private member function verifyReason.
gpgme doesn't parse the information, so we run gpg manually to verify
the revocation reason and the description.
