Gorm fields with zero values in the database aren't being scanned into search models.

Description

It appears that gorm isn't "scanning" zero values (or at least empty) strings into models. My test case sets the user name to "" and then searches for the user using the result model from the previous test. That result has a name set to "jinzhu" but the database has a name of "". Unfortunately, the result returned still has a name of "jinzhu" which isn't correct since the value in the database is "".

if user.Name != "" {
        t.Errorf("name should be set to %q but it's now: %q", "", user.Name)
}

Seems the error throw by here appears to checking the wrong object.
