Bug Description

When testing out the music scope, I noticed that the results are initially sized as if the images were 0x0, before they fill in as they are loaded. This is most apparent in the "Tracks" department display, where the results end up overlapping. This is a bit surprising, since the scope seems to show all the result images at a fixed size, so it'd be better if the result items reserved this space up front.

As well as looking a bit ugly, this means that the dash ends up requesting a lot of thumbnails that the user may never scroll down to see (some of which could slow down loading of the thumbnails that would display at the top.

Steps to reproduce, on a device running unity8 8.11+15.04.20160216.1-0ubuntu1:

1. load up a bunch of music (I used the ones from https://bugs.launchpad.net/ubuntu/+source/thumbnailer/+bug/1542175/comments/1)

2. Open the "My Music" scope.

3. switch departments and watch the images for the results load.

This is noticeable even after thumbnailer-service has cached the scaled images. I'll attach some images to demonstrate.

Screenshot taken while results for the "Tracks" department are loading. Note that the height of each result seems to be set based on the title, leaving the subtitle to overlap with the next result.

Similar for the "Albums" department. Once images start to load, only 9 results remain visible, with the rest pushed off the bottom.
