Jsonrpc: prevent while-no-input messing with jsonrpc-request

'jsonrpc-request' already has its "interrupt on user input" mechanism
base on 'sit-for'.  If called from a situation that uses
while-no-input to do basically the same, that mechanism may become
confused, so it's important to prevent that interfence.

This was confirmed to be a problem when using the Corfu completion
front-end.

Many thanks to JD Smith <jdtsmith@gmail.com> for helping me debug this
and pointing in the right direction.
