Changing attribute type from census method type to anything else breaks survey export

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Create a survey containing a matrix data type. (assign a valid census method 
to the attribute).
2. Save the the survey.
3. Edit the survey and change the attribute type to any other type.
4. Export the survey.
5. Import the survey somewhere else.

What is the expected output? What do you see instead?
Expect that the survey could be exported and imported.  Instead the reference 
to the old census method is hanging around but not included in the export.

The census method id should be cleared when the attribute type is changed to a 
non-census method type.

Change to AttributeInstanceFormField constructor:
Added else block (line 153) as per below:
        if (AttributeType.isCensusMethodType(this.attribute.getType())) {
           ...
           this.attribute.setCensusMethod(cm);
        }
        else {
            this.attribute.setCensusMethod(null);
        }
