Deleting validate_uniquess_of(:url) in validations_and_associations.md ?

[ryanzidago]

Wouldn't it be clearer to get rid of the following line of code:

it { is_expected.to validate_uniqueness_of(:url) }

in validations_and_associations.md, since urls are not expected to be unique (see link_spec.rb)?

I went on to add the corresponding code for validating the uniqueness of urls before realizing the urls do not need to be unique and uniqueness of urls are not implemented in the example_app.

@ryanzidago if this line is removed, a blank value (empty , " ") will be accepted if is unique.

@ryanzidago if this line is removed, a blank value (empty , " ") will be accepted if is unique.

How come? The presence: true prevents nils and empty strings from being accepted.
