Bug: Use default wallet for rpc commands when multiple wallets are loaded

[oren-z0]

Describe the bug
I'm using the bitcoin nodes also to develop and test some desktop wallets, which create new wallets in bitcoin-core.
This confuses the UI connection attempt.

I'm not sure if it's possible to set bitcoind so it will use a default wallet when it's not specified by the bitcoin-cli.
Specifically I would want all commands to run with -rpcwallet="".

To Reproduce
Steps to reproduce the behavior:

1. Create a new Bitcoin Core node
2. Start Sparrow wallet (with the -regtest flag) and connect to that Bitcoin Core with polaruser & polarpass credentials.
3. See error in the Polar UI

Expected behavior
Polar should just ignore other wallets.

Screenshots

Hey @oren-z0 Thanks for the feedback. This is a scenario that I have not encountered myself. Appreciate the detailed explanation. This is should be fairly easy to resolve. I'll try to squeeze it in before the next release.
