[qa] Avoid race in preciousblock test.

Browse Source 
If node 0 is sufficiently fast to announce its block to node 1,
node 1 might already have the block by the time the
node_sync_via_rpc loop gets around to node 1, resulting in the
submitblock result "duplicate-inconclusive" as node 1 has the block,
but prefers an alternate chain.
