[PATCH] gitk: Refresh the index

If one or more tracked files changed non-tracked metadata like mtime,
gitk would report it as "Local uncommitted changes, not checked in to
index" even if no actual changes have been made. (Clicking on the
"Local uncommitted changes.." entry would show the file but without
any diff.)

This refreshes the index in readdiffindex to avoid this and make gitk
behave more like "git status" instead.
