    yrno: Fix forecasts never being available because invalid
    
    yrno was never setting the "valid" flag on the main info struct, just on
    each one of the info structs created to hold the forecasts, so it was
    impossible to get the forecasts unless *another* provider succeeded.
    
    This fixes fetching forecasts for Helsinki, as METAR fetching fails and
    YR.NO didn't set the valid flag.
    
    Closes: #11
