Namespace selector does not update the function list

[LucasRoesler]

My actions before raising this issue

• Followed the troubleshooting guide
• Read/searched the docs
• Searched past issues

If I deploy functions to the default namespace and to an additional namespace, the namespace selector in the gateway UI does not appear to work. The API returns the expected result with a new function list, but he UI does not update to reflect this

In this screenshot you can see the latest API response but with the wrong function list rendered

Expected Behaviour

The function list should change to show the functions from the selected namespace

Current Behaviour

Found while walking through a demo of multinamespace support

Steps to Reproduce (for bugs)

1. Deploy on kubernetes with the latest helm chart openfaas-5.3.8, make sure to set clusterRole to true
2. Create an annotate an extra namespace

   kubectl create ns dev-fn
   kubectl annotate ns dev-fn openfaas="true"

3. use the cli to deploy left pad to an extra namespace, faas-cli store deploy Left-Pad -n dev-fn
4. also deploy a function to the default namespace faas-cli store deploy NodeInfo
5. Open the gateway ui
6. use the namespace selector to change to dev-fn
7. observer that the function list does not change, it should still just show NodeInfo

Context

Relates to #1379
