segfault introduced by #122

[kennypm]

On Gentoo, no systemd, no elogind. 0.1.5 worked as expected with the following config, though sometimes exhibited the bug addressed in #122.

hypridle.conf:

general {
}

listener {
    timeout = 61
    on-timeout = hyprctl dispatch dpms off
}

listener {
    timeout = 60
    on-timeout = hyprlock
}

stdout:

[LOG] Registered timeout rule for 61s:
      on-timeout: hyprctl dispatch dpms off
      on-resume: 
[LOG] Registered timeout rule for 60s:
      on-timeout: hyprlock
      on-resume:
