#325 - Fixed a bug that expandable draws label twice.

[njuwuyuxin]

It may cause display error in Scriptable Wizard.

In ExpandablePropertyDrawer.cs:

• When drawing expandable property, it calls EditorGUI.Foldout(). It may draw property label once.
• After that , it calls EditorGUI.PropertyField() with label override. It may draw property label twice.

This problem was not discovered in inspector for the label totally overlaped when drawing twice.
But in Scriptable Wizard, the second label can't overlap on the first label （Maybe for the indent reason)

This issue has the same problem and may be fixed, too.
#306 - Expandable Attribute label is broken in custom editor window
