> When referencing an external schema (to use foreign key references in another schema definition) and back referencing to its origin, we get an infinite recursion.
> Affects: org.apache.torque.templates.transformer.LoadExternalSchemaTransformer.transform()
> Example:
> First Schema:
> {code:java}
> <?xml version="1.0" encoding="UTF-8" ?>
> <database>
>     <external-schema filename=secondary-schema.xml" />
>     <table name="test" javaName="Test">
>         <column name="Id" javaName="Id" required="true" type="INTEGER" primaryKey="true"/>
>         <column name="Name" javaName="Name" required="true" type="VARCHAR" size="5"/>
>         <column name="foreign-key" javaName="ForeignKey" required="true" type="INTEGER" size="2"/>
>         <!-- define foreign key to secondary scheme!-->
>     </table>
> </database>{code}
> Second Schema: 
> {code:java}
> <?xml version="1.0" encoding="UTF-8" ?>
> <database
>     xmlns="http://db.apache.org/torque/5.0/templates/database"
>     xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
>     xsi:schemaLocation="http://db.apache.org/torque/5.0/templates/database
>     https://db.apache.org/torque/torque-5.0/documentation/orm-reference/database-5-0-strict.xsd" name="test" defaultIdMethod="native" defaultJavaType="object">
>     <external-schema filename=first-schema.xml" />
>     <table name="foreign-key" javaName="Test">
>         <column name="Id" javaName="Id" required="true" type="INTEGER" primaryKey="true"/>
>         <column name="Name" javaName="Name" required="true" type="VARCHAR" size="5"/>
>     </table>
>     <table name="test2" javaName="Test2">
>         <column name="Id" javaName="Id" required="true" type="INTEGER" primaryKey="true"/>
>         <column name="Name" javaName="Name" required="true" type="VARCHAR" size="5"/>
>         <column name="foreign-key" javaName="ForeignKey" required="true" type="INTEGER" size="2"/>
>         <!-- define foreign key to first scheme!-->
>     </table>
> </database>{code}
