[Table] Bad Cell Contents when we use inheritance between Stereotypes (On #MR60 with the provided StereotypeTable)

Steps to reproduce:

1. Create a new Profile, with 2 Stereotypes, A and B.

2. Stereotype A extends the Metaclass Class

3. Stereotype B Inherits from Stereotype A (Generalization link)

4. Create a Property prop, typed by String in StereotypeA.

   1. By construction Stereotype B inherits from the Property defined in Stereotype A

5. Deploy the profile

6. Now, you can create a Model, with 2 Classes. Apply Stereotype A on the first class and Stereotype B on the second Class.

7. Create a Stereoytpe Table instance

8. The new table contains the 2 classes in rows and 2 columns, as expected.

9. The Cell for representing the property defined by Stereotype A displays N/A for the Class stereotyped with Stereotype B

   The current table implements take in account the inheritance between Stereotypes. This point should be fixed.
