unselect current package if an avoided package is already selected
Patch by Anssi Hannula, fixes bug #52145 If package 'a' Conflicts on 'b', and user (or a dependency chain) tries to install both at the same time, perl-URPM will only detect the conflict if package 'a' gets selected first (this depends on hdlist order), as _set_rejected_from is only called in one direction from _handle_conflicts and it does not detect that a package it is about to reject_from is already selected. This bug currently causes a failure in urpmi handle-conflict-deps2 testcase. This commit checks if avoided package is already selected, and unselects current package in such a case
