Selecting the same option again in an OptionSelector results in that option being hidden

[Nekhelesh Ramananthan]

Steps to reproduce:
1. Navigate to the Alarms Tab and press Add Alarm.
2. In the "Occurs" optionselector, select the same day shown again.

What happens:
The day disappears

What should happen:
The day appears as the selected option

----- Way to reproduce this in the SDK (general code) ----------

Steps to reproduce:
1. Open the SDK gallery project in qtcreator via Tools -> Ubuntu Touch -> Ubuntu Touch Showcase Gallery.
2. Open OptionSelectors.qml file
3. Change the first option selector code as shown below,

OptionSelector {
               objectName: "optionselector_collapsed"
               text: i18n.tr("Collapsed")
               selectedIndex: 1
                model: [i18n.tr("Value 1"),
                        i18n.tr("Value 2"),
                        i18n.tr("Value 3"),
                        i18n.tr("Value 4")]
            }

4. Now run the gallery, and choose the index: 1 again. Notice that it disappears.

The only additional code which was added above was selectedIndex: 1 which results in this bug appearing.

Turns out this is an upstream bug since I can reproduce this in the UITK gallery code as well.

@Nicolas d'Offay, can you list which UITK rev did this bug get fixed it? As of rev 801, I still face this bug using the steps produced above. I do not think this bug is fixed.

[Nicolas d'Offay (nicolas-doffay)]

This should be fixed now. The selector refocuses on collapse as safety measure to prevent this.
