wallet: ensure bestHeight is updated before isCurrent check

In this commit, we fix an issue with the wallet's initial sync logic
where we'd miss processing all of the blocks in the chain. This can
happen if the backend is considered current while we're still catching
up. To address this, we make sure we update our best height to process
those missed blocks.
