make addrpx behavior similar to new account behavior

[jjb]

when creating a new account, presence of email validations are ignored. when adding an rpx provider to an existing account, they are not ignored.

last night i was trying to fix this and found the relevant place in the code to fix this, but now i can't find it.

if you don't even know what i'm talking about, let me know. if i figure out what my idea was, i'll share it here.

cheers,
john

maybe this will help understanding the problem:

acts_as_authentic do |c|
  c.account_mapping_mode :internal
  merge_validates_length_of_email_field_options :if => Proc.new { |user| !user.email.nil? }
  merge_validates_format_of_email_field_options :if => Proc.new { |user| !user.email.nil? }
end

The merge_foo lines are not needed for creating a new account, but they are needed for adding an rpx provider to an existing account.
