Description of problem:
The console crashes when it used with a user settings ConfigMap that is created with a 4.13+ console. This version saves "null" for the key "console.pinnedResources" which doesn't happen before and the old console version could not handle this well.
Version-Release number of selected component (if applicable):
Always, but only in the edge case that someone used a newer console first and then downgraded.
This can happen only by manually applying the user settings ConfigMap or when downgrading a cluster.
Steps to Reproduce:
Open the user-settings ConfigMap and set "console.pinedResources" to "null" (with quotes as all ConfigMap values needs to be strings)
Or run this patch command:
Console should not crash
