When `leftwm-theme apply` is called from script it wont execute a reload

[VuiMuich]

This was initially reported by @arcolinuxz on discord dm.

The following script seems not to be able to trigger a SoftReload of leftwm, the symlink to the current theme gets updated though:

#!/bin/bash
#set -e

I tested with this script on my side and everything worked fine:

#!/usr/bin/env bash
#set -e

leftwm-theme apply Forest

leftwm-theme apply basic_eww

leftwm-theme apply serika
