Add optional block to associations find method

[barrerajl]

• Call class find if id is provided
• Call find on find_some enumerable if block given
• Else return find_some enumerable (same happens in ruby by default in an array)

Thank you for this @barrerajl!

It looks as if Rails supports the following as well:

User.find do |u|                       
  u.name == "Bob"
end                                    
#  User Load (17.0ms)  SELECT `users`.* FROM `users`
#  => <User:0x000000010713fbe8 id: 16, name: "Bob">

Maybe if we're going to be adding this feature, it would be good to get this working consistently here as well?
Have added a test case, in case you're able to take a look.

Let me check. I can add some code for sure.

I made a few tweaks but looks good to go now.
Will merge and release a new version. 👍
