gerrit hooks wrong for zstream bugs

Hi, in review https://gerrit.ovirt.org/#/c/58631 the hooks are complaining that: "• Check TM::#1339464::ERROR, wrong target milestone for stable branch, ovirt-3.6.7 should match ^.*4.0.*” which is not correct as the bug is a pending clone candidate (hence TM 3.6.7) but the bug entry is 4.0 and will remain 4.0 when it is cloned, and it has 4.0 flag Thanks, michal
