revert unittests to use plain text-based LibreOfficeKitCallback

At least for now it seems that the more complex
SfxLokCallbackInterface is just an unnecessary complication for unit
tests. The performance doesn't matter, and handling all the
specialized callbacks makes things more complicated. In the future
it'd be also useful to make the tests (optionally?) use also
CallbackFlushHandler as the provider of the messages, in order
to test CallbackFlushHandler more thoroughly, so perhaps in the end
it makes more sense to keep unit tests using the plain text interface.

This reverts unittest-related parts of 3b729db05553c1a6d461fb41c89
and adds a smaller wrapper callback class that converts messages
from SfxLokCallbackInterface to LibreOfficeKitCallback format.
