do not try to promote to an older package
Patch by Anssi Hannula, fixes bug #52460 When searching for possible promotions, _handle_diff_provides() allows downgrade as well as upgrade. However, downgrade is not currently supported, and will fail early in _no_more_recent_installed_and_providing(), called from resolve_requested__no_suggests_(). As no backtracking is done for early failures in this function (should it be? dunno), the promotion gets forgotten and a failing transaction will occur. Simple fix is to only allow upgrade before doing the promotion. Patch attached. It introduces no regressions in urpmi or perl-URPM testsuite.
