Default wallet on rpc calls

[DrDBanner]

Issue

Partyman can't determine the correct wallet if Particl Desktop has connected to the already running Particl Core and switched wallets back and forth.

How to reproduce

1. Start Particl Core
2. Check status with partyman status
3. Start Particl Desktop having 2 or more Wallets and switch back and forth between them.
4. Close Particl Desktop
5. Check status with partyman status

Possible solution

• Check if there are more than 1 wallet(s) present and no default wallet is set within partyman
• Add a default wallet switch mechanism within partyman. -> "Partyman has identified the following wallets [1,2,3], which one is the default wallet you want partyman to interact with?
• Make all rpc calls with a determined wallet mandatory

Note

Since Bitcoin 0.21.0 The createwallet, loadwallet, and unloadwallet RPCs now accept load_on_startup options to modify the settings list.
