hooks are not executed on return from screen lock

[pas-calc]

Describe the bug hooks (placed in ~/.config/redshift/hooks) are not run when returning from login screen from locked session

To Reproduce lock screen (alternative wait for screensaver) and return to session (during period-change in redshift), a hook won't be run

test it simply with the debug test written as example in the man page:

#!/bin/sh
case $1 in
    period-changed)
        exec notify-send "Redshift" "Period changed to $3"
esac

to add the hook

mkdir -p ~/.config/redshift/hooks
nano ~/.config/redshift/hooks/debug-test.sh
# copy content from above
chmod +x ~/.config/redshift/hooks/debug-test.sh

Expected behavior the hook to be run on session return
