Delete payments when a publisher allowance is paid

[bumi]

Describe the bug

Deleting a publisher (i.e. nakaphoto) does not delete related payments. Currently we only delete the allowance entry not the payments.

Screenshots

• Delete the nakaphoto entry
  
• Payment still visible
  

To Reproduce

Steps to reproduce the behavior:

1. Visit 'Websites'
2. Delete an entry which has payments
3. Open the popup
4. Related (outgoing) transactions are still visible

Expected behavior

After deleting a publisher the related payments should be gone as well.

Additional context

• Allowance delete is happening here:

• In case of getting an allowance we're adding related payments here: https://github.com/getAlby/lightning-browser-extension/blob/master/src/extension/background-script/actions/allowances/getById.ts#L32-L36
• Getting all related payments and delete them: https://dexie.org/docs/Collection/Collection.delete()
