Fix placesNearby rankby parameter

[dconde7]

Changed ‘rankBy’ parameter to ‘rankby’. Using ‘rankBy’ always returns zero results.

Added test case for nearby places search ranked by distance.

Documentation at https://developers.google.com/maps/documentation/javascript/places should also be updated. Already submitted feedback.

We found a Contributor License Agreement for you (the sender of this pull request), but were unable to find agreements for the commit author(s). If you authored these, maybe you used a different email address in the git commits than was used to sign the CLA (login here to double check)? If these were authored by someone else, then they will need to sign a CLA as well, and confirm that they're okay with these being contributed to Google.

I am the commit author and sender of the pull request. Both actions were done using the same name, email address and github account name that is in the CLA.

Thanks a lot!

BTW the docs you linked to are for the JavaScript library which uses rankBy, so those are correct. Web services uses rankby, so your fix for this library is correct.

Could you please also update the package on npm?
