    Revert "Frontend-GNOME: restore cursor position in MessageTextView"
    
    This reverts commit 22be95388e0aaae195538a62c8637f91db888692.
    
    Turns out this change wasn't useful for blind persons as they rely on the
    position of the cursor at all times. The red marker line as visual indicator
    for marking were read messages end and new messages start is not useful to them
    as the red marker line "jumps" from the current/last position to the bottom of
    the chat if you leave the chat. This logic makes sense because the human eye can
    easily jump many messages and still knows what is going on. For blind persons
    they have to follow and go through each message one by one, otherwise they will
    be lost of what happened in between. The cursor gives them the full control over
    where they are and where they want to move next to, while an automatic jump
    is completely confusing and useless to them.
    
    The idea here was to align the "already read messages" logic from the red marker
    line with the cursor position but instead it became more confusing and harder
    for blind people. Thus this change is reverted and the exact position of the
    cursor needs to be retained even across restarts of Smuxi, to be an improvement
    for blind users.
