Install and uninstall have different casing sensitivities

[isc-dchui]

Describe the bug

If module.xml defines a package as MyPackage.MySubPackage.PKG but the actual classes are MyPackage.MySubpackage.MyClass.cls, then install will work just fine, but uninstall will fail to find the classes and fail to remove them. Uninstall will actually succeed without any errors in this case.

To Reproduce

Steps to reproduce the behavior:

1. Define a module.xml with a package resource like MyPackage.MySubPackage.PKG
2. Include classes like MyPackage.MySubpackage.MyClass.cls, with the casing difference
3. Load the module
4. Uninstall the module
5. Note the classes don't get deleted

Expected behavior

The classes get deleted even though the case is different

System information (please complete the following information):

• IPM version: 0.10.6
• IRIS version: Unknown
• OS: Unknown
• Docker or local: Unknown

Workaround

Ensure your package and classes are actually named with the same case.

Dev notes

%IPM.Storage.ResourceReference.GetChildren() uses %Library.RoutineMgr_StudioOpenDialog, which is case-sensitive. We should replace with a query on %Dictionary.ClassDefinition instead.
