fix: create method loading relationships REFS #61

the  method in the  package simply refreshed the model
post create and returned it to the calling function, while this will load the
identifier but it won't load any dynamically configured relationships

we previous fixed this by introducing a _base_get_query in issue #41
the create method now calls the  method to get a fully populated
model
