[FIX] web: avoid infinite pending state in case of RPC call fail

If the RPC fails, the deferred is never resolved nor rejected,
so the deferred given by willStart will stay in a 'pending' state

As the deferred is expected to be resolved or rejected to launch the
systray to continue, we have to catch this case too.
