BE modul scheduler should toggle some fields depend on selected task-type option. This functionality is a bit broken.

1. Input 'task frequency' and 'task end' always shown on start editing (should be hidden if current 'task type' is 'single')
2. Input 'task frequency' toggles incorrect (toogle should regard selected option on change 'task type')
3. Input 'task end' get not toggled (identifier missing)
4. Checkbox 'task multiple' should be available (Allow parallel execution also for single tasks)

To test, ensure, your browser loads/refresh changes on Scheduler.js
