ofver must deal with the correct setting of Django persistence driver for pypelib

[lbergesio]

Django persisten driver models of the library have the app_label and db_table meta variables set to "pypelib". This have to be modified by ofver.

More ofver the value depends on the installation. Production, pre-prduction and sdks have different combination of values and so the tables in the database are called differently. Correct values should be defined to the ones in production. Nevertheless it is possible that other installation have different values, reason why ofver, before updating the .deb packge of pypelib, has to checj the values previously used.
After updating the library, set them again.
