Hand the whole reflog to GetReflogCommitListDisplayStrings

The reflog commits context slices the visible lines out itself and passes
only those, so the function has no way to look at the rest of the list. A
following commit needs the oldest entry to work out how much width the
date column needs. Take the whole list along with the range to render, the
way GetCommitListDisplayStrings already does.
