codeclimate/codeclimate-rubocop

This cops checks for code that can be changed to `blank?`.
Settings:
    NotNilAndNotEmpty: Convert checks for not `nil` and `not empty?`
                       to `present?`
    NotBlank: Convert usages of not `blank?` to `present?`
    UnlessBlank: Convert usages of `unless` `blank?` to `if` `present?`

### Example:
    # NotNilAndNotEmpty: true
      # bad
      !foo.nil? && !foo.empty?
      foo != nil && !foo.empty?
      !foo.blank?

      # good
      foo.present?

    # NotBlank: true
      # bad
      !foo.blank?
      not foo.blank?

      # good
      foo.present?

    # UnlessBlank: true
      # bad
      something unless foo.blank?

      # good
      something if  foo.present?
