Media details: Nearby query sent every few seconds, depsite no use for the results

[nicolas-raoul]

Steps to reproduce:

1. Open app to your contributions activity (default activity)
2. Open one of your contributions
3. Start observing logcat

You will observe that every few seconds, an HTTP query like this is made:

10-30 22:12:45.708 16101 16101 D LocationServiceManager: on location changed
10-30 22:12:45.709 16101 16641 D NearbyController: Loading attractions near lat/lng: ([...],[...])
10-30 22:12:45.709 16101 16641 D OkHttpJsonApiClient: Fetching nearby items at radius 0.3
10-30 22:12:45.709 16101 16641 D OkHttpJsonApiClient: CUSTOM_SPARQLfalse
10-30 22:12:45.745 16101 16641 V OkHttp  : --> GET https://query.wikidata.org/sparql?query=SELECT[...]

The Media details activity (screenshot below) does not show any information about nearby items, nor is it supposed to.
So I don't think there is a need for these infrequent requests, they use battery and data and server resources for nothing.
