Huddled flowview icons when shown for first time

[Francis Ginther]

[Impact]
Arrangemenet of flowview applications icon incorrect.

[Test Case]
From unity/manual-tests/Flowview.txt:
Test Flowview Workin
--------------------------------
This test shows that the coverflow shows up and works when requested by the backend.

Setup:

Actions:
#. Start with a clear screen
#. Press Super
#. Open a lens which uses flow

Expected Result:
  The flow view should be visible with icons folded at the edge of the screen.

[Observed Results]
When the appication lens was first loaded, all the downloadable icons were huddled on the right edge (see screenshot). Afterwards they were centered but only 6 were displayed unless a search string was entered, at which time the number of icons shown expanded.

This only happens the first time the application lens is shown. Can be reproduced immediately after a reboot.

Reproduce with nvidia driver 304.43-0ubuntu1. See screenshot-nvidia.
