QML UI Mobile: correct margins on log page

Also a developer likes to see a nicely formatted page, so correct
some bugs in margin handling on the log page. There was a strange
multi-line whitespace on the top of the list, and the total width
of the page was (initially) a little smaller than full page, so
showing a small strip of the page left on the pageStack. This
just looks weird. So again, cosmetics only.
