surrounding_text not getting updated when entering keycodes

[grelltrier]

When a keycode is sent to the wayland compositor, the surrounding text is often changed. The compositor does send an surrounding_text event as a response, but for some reason it seems like it is the old string.

This might be an issue with the implementation of phoc and not fingerboard, but I need to investigate it more.

This will become an issue once the interpreter uses the info about the surrounding text for its predictions of the next word
