These two views only ever appeared as tabs (of the files and commits
panels), so unlike the other side views they had no title set; the tab
strip supplied their label. Once a tab can be promoted to its own panel
they can appear without a tab strip, so set their titles like the others.
This has no effect in the default layout, where both are always tabs.
