test/extended/image_ecosystem.NewSampleRepoTest(): fix django-psql

[nalind]

The template for django-psql-example apps doesn't specify a branch, but the default branch no longer contains anything.

Update the test to supply "2.2.x" as the branch name to use in the https://github.com/sclorg/django-ex.git repository.

There are other references to this repository in examples and samples that I didn't touch. Should they be updated to refer to the same tag that this one uses, where it does?

Rebased. The go-verify-deps is complaining about go.mod mentioning github.com/openshift/api v3.9.0+incompatible, even though go.mod also overrides it with a "replace" directive later on.
