Code review comment for lp:~mpt/libusermetrics/1286276-no-data-sources

That's because the greeter hides the Infographics component if the string is ""
http://bazaar.launchpad.net/~unity-team/unity8/trunk/view/head:/qml/Greeter/Infographics.qml#L76

We can fix that either by not having that condition in unity8 (unsure why it was there though, subscribing Michael who seems to have added it and might know) or by changing the "" here to be " " (which feels a bit hackish but should work)
