Do not use @all account for reset_xxx_list operations
When resetting lists, condenser uses the @all account as a
following parameter for the custom_json operation.
Although the @all account has not been used for a long time, it is an (unknown) user-controlled account (not a system account) and we have no guarantees as to how this account might act in the future or how operations involving this account could be managed by apps that consider it as a standard account.
The simplest solution is to replace the referenced account with @null.
An even cleaner solution would be to not require or ignore the "following" parameter for reset operations. But that requires a change of the Hivemind code.
