Shazron Abdullah resolved CB-1752.
----------------------------------
Resolution: Not A Problem
This is not a Cordova API issue ultimately. This is an iOS issue where you need
to enable background location tracking. See UIBackgroundModes:

> In an App latitude, longitude, altitude, speed and timestamp is stored into a
> database table (W3C Web SQL Database) But this error is also there if I write
> the values I need into the DOM.
> As long as the App is in foreground everything works fine.
> If App is going into background mode (location) and is reopened a time later
> everything without the speed is going into table.
> There's only one codebase for tracking (navigator.geolocation.watchPosition)
> -> the watchPosition getAll the Trackpoints after I reopen the App.
