SentMessageClient class missing

[brilnius]

Glad to have found this gem! :-)

When using the example in readme:
result = account.sent_messages
I got this exception:
NameError: uninitialized constant Esendex::Account::SentMessageClient

After a glance at the change history, it seems SentMessageClient was indeed removed some time ago.
What was the reason? Is SentMessageClient supposed to "come back" one day?
If not, the readme should be updated (and also remove the Account.sent_messages method).

Hi @brilnius

Thank you for the feedback! It looks like we inadvertently introduced a regression merging in quite an old PR. I'll raise a bug card once I've had a chat with people in the team when I'm not quite so lonely in the office. It's a little quiet until January heh.

I'll also keep you posted and update the issue with the outcome once I know what direction we're taking with this. Thank you again!
