Description of problem:

Dashboard pods are reporting these lines of error in their logs:

Failed to get groups: TypeError: Cannot read property 'includes' of null

four clusters out of four I've checked report the same line of error. 

Prerequisites (if any, like setup, operators/versions):

RHODS installed

Steps to Reproduce

1. Go To OCP Console > Workload > Pods
2. open one of the dashboard pods
3. check the logs (rhods-dashboard container)

Actual results:

Failed to get groups: TypeError: Cannot read property 'includes' of null

Expected results:

No errors

Reproducibility (Always/Intermittent/Only Once):

Always

Build Details:

RHODS v1.8.0-14

Workaround:

Live build:

quay.io/lferrnan/rhods-operator-live-catalog:1.12.1-admin-group

Testing instructions:

1. Install the live build
2. Check that there is no Failed to get groups: TypeError: Cannot read property 'includes' of null message in the fresh install.
3. If the group is not created, a new desriptive error would trigger to indicate wich group should you create. Error: Failed to retrieve Group dedicated-admins, might not exist.
4. Create that group to dismiss the error.
5. Check that if you remove groups-config ConfigMap you will have a descriptive error. Error: Failed to retrieve ConfigMap groups-config, might be malformed or doesn't exist.
6. If you add it again, and in the second configmap (usually rhods-groups-config) you change the admin_groups field to 'system:authenticated' you will have a descriptive error. Error: It is not allowed to set "system:authenticated" or an empty string as admin group
