[gnome-continuous-yocto/gnomeostree-3.28-rocko: 2757/8267] bitbake: toaster: move MostRecentBuildsView to its own widget

[Emmanuele Bassi <ebassi src gnome org>]

commit 8ba7ccd25247539cbea8786026b375a2c9169aad
Author: Michael Wood <michael g wood intel com>
Date:   Mon Sep 26 13:59:29 2016 +0300

    bitbake: toaster: move MostRecentBuildsView to its own widget
    
    This view is specific to the builds dashboard rather than gernic api so
    like ToasterTable and ToasterTypeAhead we class it as a widget as it has
    a single purpose. Also clean up some flake8 identified issues.
    
    Original author of the code moved in this commit is Elliot Smith.
