added strict param. It's able to you use strict has_role?

[sunchess]

class User < ActiveRecord::Base
  rolify strict: true
end

@user = User.first

@user.add_role(:forum, Forum)
@user.add_role(:forum, Forum.first)

@user.has_role?(:forum, Froum) #=> true
@user.has_role?(:forum, Froum.first) #=> true
@user.has_role?(:forum, Froum.last) #=> false

I.e. you get true only on a role that you manually add.

This is a good PR but the TravisCI build is currently failing a test for Mongoid. If you can correct this, we'll merge this into the project.

Hm.. sorry but on my local laptop I haven't errors on tests. I really want to.
My PR not have changes gemfile or any config. Why can by the error "Don't know how to build task 'db:create'"?
