07c4838 Always return true if AppInitMain got to the end (Matt Corallo)
Pull request description:
This should fix a rare zapwallettxes failure on travis, but also avoids having init operations (re-adding wallet transactions to mempool) running after RPC is free'd. I believe this was the failure at https://travis-ci.org/bitcoin/bitcoin/jobs/311747844 (from #11605).
