[bugfix] station name was in dictionary instead of a list item for autopickstations return value

Old implementation of autopickstation returned a list containing a dcitionary with results as a first value and a string with the station name as a second value. The new version used to return a single dict with a key/value station name pair, which the calling code could not unpack. The new implementation now also returns a list with picking results and station name.
