telepathyClient: Fix auto-scroll to bottom

Browse Source 
Instead of keeping track of the old adjustment.upper keep track of the
old adjustment.value that corresponded to the bottom scroll position.

This fixes the integrated chatview not always scrolling to the bottom
by removing the assumption that page_size is constant between updates,
which is not the case as the view is presented in various different ways.
