a1e653828btest: Add test for migrating default wallet and plain file wallet (Andrew Chow)bdbe3fd76bwallet: Generated migrated wallet's path from walletdir and name (Andrew Chow) Pull request description: This PR fixes an assertion error that is hit during the setup of the new database during migration of a wallet that was not contained in a wallet dir. Also added a test for this case as well as one for migrating the default wallet. ACKs for top commit: ryanofsky: Code review ACKa1e653828bfurszy: ACKa1e65382Tree-SHA512: 96b218c0de8567d8650ec96e1bf58b0f8ca4c4726f5efc6362453979b56b9d569baea0bb09befb3a5aed8d16d29bf75ed5cd8ffc432bbd4cbcad3ac5574bc479
