Fix names of relationships in amodels
Fix names of relationships in amodels

Some fields have name = `'+'`, so we get empty names of relationships.
I suggest to use the following pattern for such relations: `_{module_name}_{model_name}_{field_name}`.
`{field_name}` at the end is necessary because some models may have multiple relations to one model.
