Make sure exception is fully logged when rescued

I was tempted to actually raise the exception, but it might not be safe since we don't know what goes on under there.

The logged exception will look like this:

    An error has occurred during geocoding: Address: 'kozana 115'. Provider: 'lol'. Exception:
