Bulk invitations sent to already confirmed users

[tolomaus]

The problem is that the confirmation_token is emptied when the user confirms and the bulk_invite filters on empty confirmation_tokens only:

users = User.where(:confirmation_token => nil).order(:created_at).limit(params[:quantity])

Simply adding :encrypted_password => nil to the where cluase solves the problem:

users = User.where(:confirmation_token => nil, :encrypted_password => nil).order(:created_at).limit(params[:quantity])
