Added new methods to builder (#748)

[maicol07]

The following methods have been implemented from #748:

• unsigned_big_integer
• id
• foreign_id
• foreign_id_for
• foreign_uuid

[josephmancuso]

Just have to fix the tests

[maicol07]

@josephmancuso should be fixed!

[maicol07]

This time they're fixed for good!

[josephmancuso]

I don't see a test for the foreign_id_for one. Just need to make sure the model name and primary key is correctly formed.

More tests the better. Allows me to make changes with comfort

[maicol07]

How can I create a Model in tests? Should I just have to create a new model instance?

[josephmancuso]

Yup just make a model as you normally would inside the test file and use it.

Example: https://github.com/MasoniteFramework/orm/blob/2.0/tests/mysql/relationships/test_belongs_to_many.py#L16-L23

@josephmancuso done!
