Bug with Self references

[josejachuf]

I used this characteristic in previous projects, but in a new project, with the latest version of Emmett, an error occurs.

class Person(Model):
    name = Field()
    refers_to({'father': 'self'})
    has_many({'children': 'self.father'})

Indicates that there is no Person. I would not know what version it began to fail

Found the culprit: https://github.com/emmett-framework/emmett/commit/217041205d8ed6f63d45a8a541cb3bd0f6c4b312#diff-06b6fce4899f13c7d0951ab3969d7a7f30f4f9943223f60601add41b73bfcb60L370

It seems broken just for 2.4.x and above, I should be able to make a patch release in the following days.

This is now fixed in master and 2.4.14
