Bug 1881222

This is partially addressed by changes that are already merged for 4.6, but it can still occur with a few tweaks to the test setup. Posted a PR just now to address that as well.

With this issue fixed, the last list of subscriptions should look like this:

NAME                                                   PACKAGE         SOURCE               CHANNEL
testoperatora-v1.2-test-catalogsource-test-namespace   testoperatora   test-catalogsource   v1.2
testoperatorb                                          testoperatorb   test-catalogsource   v4.1-eus

and testoperator b should still be satisfied by v4.0.1:

$ kubectl -n test-namespace get sub testoperatorb -o jsonpath='{.status.installedCSV}'
testoperatorb.v4.0.1

Please ignore if one of the test operators crashes on startup, which may result in a CSV (appropriately) showing phase Installing. These aren't intended to be functional operators, only to test dependency resolution behavior.
