Return resourceversion too old error to UI instead of logging (#667)

* Return watch error instead of logging it

The UI needs to know about watch error like `resourceversion too old` so
we need to return it.

* Sort by resourceVersion as number

The UI makes some assumption on resourceVersion. It assumes they are a
number and they are ordered by the number value. We'll want to fix this
at some point most likely but for now let's give something in a way that
UI wants.

* Remove -d suffix

After much testing, a delete of an object seems to have its own
resourceVersion so we don't need the -d suffix, we can simply use the
new resourceVersion.
