test: drive the jtx reconnect through a fixture server

The first-request test slept 4 s against the server's 3 s deadline, leaving
1 s for the server's timer to fire on a loaded runner before the request
arrived; it now sleeps 8 s. The keep-alive test compared reconnects() to 0
across both requests, so a legitimate reconnect on a slow first request
failed it; it now checks the count is unchanged across the idle gap.
