When loading up users page as an admin, show all projects

[jmgasper]

Expected behavior

Admins should be able to see all projects in the project dropdown on the /users path.

Login with mess / appirio123

The project list should load via a URL like:

NOTE that this is ONLY for admin users. The functionality for managers / PMs / copilots should remain the same

https://api.topcoder-dev.com/v5/projects?sort=lastActivityAt%20desc&status=active

Actual behavior

The project list loads with memberOnly=true as a parameter:
