Closes #30

@kjozwiak mind asking someone of the team to create random channels to test the edge cases?

• very long name (as we tested https://longextendedsubdomainnamewithoutdashesinordertotestwordwrapping.badssl.com/ for the bravery panel)
• l10n (non-ASCII; french and CJK - important to test cases in languages which do not have whitespaces)

@srirambv can you add one more case that involves changing Advanced Settings and ensuring the entries are still being added into the ledger table? Other then that, everything looks good 👍

Great idea... I'll create a few channels with the above suggestions and add the credentials into 1Password.
