Fix endless redirections when accessing user OAuth applications when they are disabled
What does this MR do?
This MR fixes a bug where the browser would be redirect endlessly when attempting to access the user's OAuth applications when an admin has disabled this system-wide setting.
Are there points in the code the reviewer needs to double check?
I assume disabling the nav button is better than showing a page that says, "OAuth applications are disabled by the admin."
Why was this MR needed?
Lots of users were confused when they hit endless redirect errors.
