    graphHopper: Don't fold keep left/right instructions
    
    In #171 we introduced "folding" of routing instructions
    for "continue straight" and keep left or right instructions
    to work around GraphHopper giving a lot of extra instructions
    while staying on the same road number/name.
    This has tended to take away a bit _too_ much, such as
    "keep right" instructions when exiting a highway (and the
    offramp has the same ref number as the main highway).
    So, only fold exact "continue on street" instructions now.
