Inheritance of @UiDescriptor does not make sense

[andreybpanfilov]

Environment

• Platform version: 7.2.4

Description of the bug or enhancement

Scenario:

package domain1

@UiController("domain1_Entity")
@UiDescriptor("domain1-entity.xml")
class EntityController {

}

package domain2

@UiController("domain2_Entity")
// here we do not override UiDescriptor annotation because 
// we expect it should be inherited from domain1.EntityController
class EntityControllerExt extends domain2.EntityController {

}

• Expected behaviour: domain2_Entity controller uses /domain1/domain1-entity.xml as template
• Real behaviour:

Caused by: com.haulmont.cuba.core.global.DevelopmentException: Template is not found /domain2/domain1-entity.xml

Note: CUBA Studio assumes that no more than one controller is associated with screen descriptor. So you may have problems with screen designer functioning for such shared xml descriptors.
