QmlDesigner: Fix EasingCurve editor

Due to a behavioral change in QTabBar the tabs to choose between the curve editors "factory presets" and "custom presets" got lost.
Reordering the function calls made it appear again.
Prevent the user from assigning the same name to different easing curves.

Fixes: QDS-7721
