fix: Fix hide_on_ok when user or system session is ignored

In case of an user ignoring the failed system or user units, hiding of
the waybar module did not work.

Ensure that the ignore case of a system or user bus is reflected
correctly by determining the configuration.

Fixes [1] where regression was introduced in [2].
