Enum matcher should check for _prefix and _suffix

[tejasbubane]

define_enum_for matcher should also have an option to check for _prefix and _suffix. Something like this:

conversation.rb

class Conversation < ActiveRecord::Base
  enum status: [:active, :archived], _suffix: true
  enum comments_status: [:active, :inactive], _prefix: :comments
end

conversation_spec.rb

expect(Conversation).to define_enum_for(:status).with([:active, :archived])
                                                .and(_suffix: true)

expect(Conversation).to define_enum_for(:comments).with([:active, :inactive])
                                                  .and(_prefix: :comments)

Wow. What did they do to that API?

Well... anyway... I think in order to test that option, I'll have to reimplement how define_enum_for works. ActiveRecord keeps track of which columns are enum columns by storing them in a class-level defined_enums hash. Each key is the column and each value is an array of possible values that the column takes. In this case, _prefix and _suffix change which methods get created, and that information is not stored in defined_enums. So what I may have to do here is change the matcher so that it checks which methods get created as well.
