Fixed problems with locale directories

I don't know what's happening, and i'm not sure this fix is appropriate (since if it was really a bug it should have been caught much earlier).

I'm using the library, and the application is running inside Vagrant. Now I get this exception:

     /vagrant/vendor/pear-pear.horde.org/Horde_Imap_Client/data/Horde_Imap_Client/locale is not a directory

The translations are in */vagrant/vendor/pear-pear.horde.org/Horde_Imap_Client/data/locale*, so that's why I tried to fix the path by removing `Horde_Imap_Client`.
