Portal TestSecurity Unit Test Flake

[Ben Vesel]

There appears to be a flake with one of the portal Unit tests: TestSecurity/elevated/main.js. It fails rarely, but it can be reproduced with the following code:

while true
do
  go clean -testcache
  go test -timeout 30s -run ^TestSecurity$ github.com/Azure/ARO-RP/pkg/portal
  echo $?
done

After a bit of time, you will see failures of the following:

--- FAIL: TestSecurity (0.30s)
    --- FAIL: TestSecurity/authenticated/main.js (0.01s)
        log.go:89: audit payload type cast failed
