Arguments that held the same name as one of the default commands were filtered out, causing issues.
For example `next build build` would get rid of the second `build` parameter.

After discussion, I added falling back to fetch based pinging when the WebSocket fails to connect. I also added an example of how to proxy the onDemandEntries WebSocket when using a custom server. Fixes: #6296
Closes: #6244
This will block the following keys:

NODE_.+

There doesn't seem to be a way to simulate a failed build or else I'd add tests for it.
* Set default `Error` status code to 404
This is an appropriate default behavior because:
1. When the server encounters an error, the `err` property is set.
2. When the client-side application crashes, the `err` property is set.
This means the "only" way to render the `/_error` page without an error
is when a page is not found (special condition).
