Bug 1921720: fix sig-cli flakes

This fixes two most frequently failing problems in our CI:
1. oc observe can spit 'Nothing to sync' if it doesn't find
anything and that is equally valid as 'Sync ended'
2. oc adm new-project frequently fails on timeout when
waiting for project deletion, so I'm bumping this to 2m.
