Fix separate routine/exception handling to ensure that GeoPy does not crash the thing

[jinjirosan]

Multiple times GeoPy errors (e.g. no address/location) resulted in total stop of dataflow. So fix exception handling to only affect the GeoPy data.

update: geopy is using gps coords to translate to nearest real-life address. When the baby carriage is indoors the gps fails the get proper coords, reverting to zeros, geopy crashes and the routine crashes all the data collecting and transmitting stops.
