load_wallet is not tested

[tcharding]

Context

We have a few functions that are not tested, some of these (e.g., load_wallet) require starting bitcoind running an RPC command, restarting bitcoind and verifying the desired state.

Possible solution

• Add a second binary to the integration test crate which calls the methods to test that require a restart (could use command line args so the same crate can run the command and run the verification command (i.e., cargo run -- --load-wallet and cargo run -- --verify-load-wallet)
• Patch the run.sh script to start bitcoind run the new crate with --load-wallet
• and restart bitcoind and run crate with --verify-load-wallet

There may be other ways to solve this, feel free to be creative.
