Dashboard auto-refresh does not work in Firefox

Description of problem:

Auth-refresh (when OCP token expires) implemented in RHODS-5931 seems not working in Firefox. The fix leverages on "session storage" to store odh.dashboard.last.auto.refresh (last auto refresh), but  Firefox browser doesn't store that value.

That's what i see in the browser console:

When running in Chrome, it shows a date properly.

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

Steps to Reproduce

1. make the Openshift Oauth expiring in 2 minutes (not to wait 24hours)

1. log in RHODS Dashboard with a basic user user1

1. create a DS project and wait until token expires the first time

keep waiting for other 2 minutes to make the second expiration happening in one hour

Actual results:

• result for step 3: After 2 minutes, I started seeing errors in the dashboard UI: see image "start-failing.png" 

• result for step 4: nothing happens (ok)

Expected results:

• result for step 3: the dashboard automatically reloads

• result for step 4: nothing happens

Reproducibility (Always/Intermittent/Only Once):

Always using Firefox browser

Build Details:

RHODS v1.21.0-21

Workaround:

reload the page
