Bug 1829225: Increase waiting time for namespace deletion in project test
Bug 1829225: Increase waiting time for namespace deletion in project test

The waitForOnlyDelete() waits only 30s for the project being deleted.
The e2e logs shows that in ~18% of e2e tests, the deletion takes longer
than 30s, presumably because of GC cleaning up the namespace.

In those cases, the cleanup takes 35-40s.
