Description of problem:
The guided rules in guvnor 5.x are not correctly migrated when they use the category feature to inherit from other rules. The migrated rules does not extend the rules they should according to category setup in 5.x.

For example when you have a BRL 'rule A' in category 'someCategory':
    rule A
      when
        Person()
      then
    end

and then 'rule B':
    rule B
      when
        Driver()
      then
    end

and in Guvnor 5.x you setup (in package edit view) that all rules in that package and in category 'someCategory' (that includes rule A) should extend 'rule B'. So in the end the 'rule A' will fire only when there is a Person() fact and also Driver() fact (drive got there from 'rule A'). After the migration I would expect that 'rule A' should have declared (in DRL) that it extends 'rule'.


Version-Release number of selected component (if applicable):
6.0.0-ER1#1


How reproducible:
Always


Steps to Reproduce:
1. Download and unzip the attached repo.
2. Run the migration tool with the above repo as input.
3. Look at source of asset 'guvnor-jcr2vfs-migration/org.guvnor.example2/src/main/resources/BRL in category.rdrl'


Actual results:
The rule does _not_ extend 'rule2'.


Expected results:
The rule should extend 'rule2'.
