[preview] Hook back to print_special_text

It was changed to print_real_text in caefa4ff, and since that, previews for messages that contain some text besides of the link do not work.

This has a reason, we base logic ( in accept_uri() ) on the knowledge of the whole message. this extensionpoint does not give us the whole message, only a fragment, which changes the behavior of the plugin.

also in the next Gajim version 1.4, this plugin does not exist anymore.

At this point i don’t want to introduce features into 1.3 or change the behavior of code which is 5 years old, only to lose it again in the next version.

Feel free to look into the 1.4 branch on how this could be implemented there.
