Tests: Enhance robustness of stdout driven waiting state in Sikuli based tests.

Some tests were randomly passing, because from time to time waiting for idle was skiped. It was combination of multiple problems :
- buffering on stdout (now use readline + flush for each write to log)
- it is sometime required to wait for activity before waiting for timeout added "WaitForChangeAndIdle" to "stdoutIdleObserver"

widget_desc("ListSwitch") {

    ListSwitch widget displays one item of an HMI:List depending on value of
    given variable. Main element of the widget must be a clone of the list or
    of an item of that list.  

    Given variable's current value is compared to list items
    label. For exemple if given variable type
    is HMI_INT and value is 1, then item with label '1' will be displayed.
    If matching variable of type HMI_STRING, then no quotes are needed. 
    For exemple, 'hello' match HMI_STRING 'hello'.
