QQuickToolTip: prevent closing after invisible tooltip created

Since all items using ToolTip attached property share the same ToolTip
item, a dynamically created invisible Tooltip may unexpectedly close
the current visible ToolTip.

Fix this issue by checking the parent of ToolTip when trying to close
it
