[FIX] web: trying to create record based on name_create w/o _rec_name

There are orm models that don't have _rec_name defined. The orm doesn't
allow creation of record via name_create if _rec_name is not defined in
the model. This commit considers this fact, such that if name_create
returns false, we don't proceed on displaying the non-existing record.

Note: _rec_name defaults to 'name' if not specified so only few models
don't have _rec_name.
