Avoid aborting Joomla on any DB errors that forbid executing the Database / Fix

In case of a manual upgrade from Joomla 2.5.17 to J3.2.1, it happens that some tables or columns are not present in the DB before that the DB / Fix is applied and therefore may cause DB Errors.

To allow using the Database / Fix functionality, it is important that this intercept all kind of DB errors.

This is why we added a try/cath on the loadObject that allow have access to the Extension Manager / Database / Fix action.
