Clean up console debug logs

**Describe the bug**
Some debug logs should be removed to avoid cluttering the console of browser, like dumping data on every change of the fields.
_I know there are filters._

**To Reproduce**
Steps to reproduce the behavior:
1. Use the wallet.
2. Observe some unnecessary logs are dumped into the console.

**Expected behavior**
The console is not filled with too many debug log lines.

**Additional context**
_Also make sure that the sensitive contents are NEVER EVER dumped into the console._

Start by reproducing the wallet behavior in a browser and searching the JavaScript sources for console debug output triggered by field changes. Review each relevant log for unnecessary or sensitive data, remove the clutter, and verify that wallet contents are never printed to the console.
