Description of problem:
If a custom project-request template is defined and a group definition is added to it, when the template is invoked due to a new-project request it fails with:

'Error from server (InternalError): Internal error occurred: the server could not find the requested resource'

Version-Release number of selected component (if applicable):
OCP 3.11 (tested with OCP 3.11.51)

How reproducible:
Always

Steps to Reproduce:
1. Create a new template like this:

$ oc project default
$ oc create -f template.yaml

2. Edit projectConfig.projectRequestTemplate in /etc/origin/master/master-config.yaml to point to 'default/project-request'.

3. # /usr/local/bin/master-restart api api
   # /usr/local/bin/master-restart controllers controllers

4. oc new-project test

Actual results:
Error from server (InternalError): Internal error occurred: the server could not find the requested resource

In the api logs:

delegated.go:243] error creating items in requested project "test": the server could not find the requested resource

Expected results:
project being created.

Additional info:
Same template definition was tested in OCP 3.10.45 successfully.
