Subject: [cuirass] Fetch worker ensure-path exception.

Hello,

The "ensure-path" RPC that is used by the cuirass-remote-server process
sometimes raises a &nar-error condition.

According to Ludo on #guix, this might be caused by a crash on the
guix-daemon side causing it to hang up prematurely.

Thanks,

Mathieu

Hello,

Still not sure what's causing this issue, but I catched this exception
in c832d1523d094b21e7c640115cd6158346bbc54d to keep the remote-server
fetch thread alive.

Thanks,

Mathieu
