TextEdit: Fix persistentSelection for readonly controls

TextEdit items with readOnly:true do not clear the selection on losing
focus which is expected with persistentSelection:false.

The reason is that a readonly TextEdit does never show a blinking cursor
and thus the selection clearing within setCursorVisible never happens.

This change adapts the implementation from TextInput.
