fix(ui5-timepicker): fix error thrown upon selection from the clock (#…

…9541)

Previously when selecting a time from the clock there was an error being thrown due to a check in the TimePickerClock class.
The reason an error was thrown was due to a check if a radius property was absent from an internal object, which in some cases was yet undefined, therefore trying to access that property resulted in an error.
With this change we fix that.
