fix: Fix removal of entries in account file

Commit 81f92f1fe introduced a selective update mechanism to
_accounts_save() to prevent overwrites when running multiple instances
by only modifying the specific account being saved.

Commit 5c484c fixed a problem with that commit regarding empty accounts.

It turns there was another bug introduced:
The new implementation only set the keys that existed in memory.
So removal of keys was not possible anymore.
