Change in cordova geolocation plugin

Cordova plugin version bump

[Grubba27]

I'm not so happy bumping from v2.x -> v5.x

[StorytellerCZ]

I think updating to (2.4.3)[https://github.com/apache/cordova-plugin-geolocation/blob/master/RELEASENOTES.md#243-apr-27-2017] is without a problem. After that 3.0 looks fine. 4.0+ I think would require a major version bump as it removes deprecated platforms. 5.0 I think will be from Meteor 2.14.

So this part will have to be bumped:

api.versionsFrom("METEOR@1.2");
  api.use("isobuild:cordova@5.2.0");
