matcher factory extension generation buggy

[abelhegedus]

In some cases (I don't have a way to reproduce it, although it occurred twice in the last two days), the code generator doesn't clean the matcherfactory annotations but transforms them from the correct:

<extension
         id="testing.queries.RecordRoleValue"
         point="org.eclipse.viatra2.emf.incquery.matcherfactory">
      <matcher
           factoryProvider="testing.queries.recordrolevalue.RecordRoleValueMatcherFactory$Provider"
            id="testing.queries.RecordRoleValue">
      </matcher>
   </extension>

to the mind boggling:

<extension
         id="RecordRoleValue"
         name=""
         point="org.eclipse.viatra2.emf.incquery.matcherfactory">
      <matcher
            id="testing.queries.RecordRoleValue"
            factoryProvider="testing.queries.recordrolevalue.RecordRoleValueMatcherFactory$Provider">
      </matcher>
   </extension>

Subsequent code generation rounds seems to transform the correct extensions of the last round to the strange version and creating new correct ones.

We managed to reproduce it deterministically:

• the problem occurs when the package name is the same as the project name

For example, testing.queries

Fixed in master.
