schema report can't view latter class properties if there are two classes with same name

[sparkliu]

1. Create a feature source which contains two same-name classes (under different schema).
2. Try to use schema report to view schema of feature source. Two feature classes are in the list.
3. Try to expand data properties of the second one. You'll find the data properties of first one is expanded instead.

This is because the page only uses class name as ID so it will cause a problem when duplicate name exists. Fix uses schema ID as well.
