stats: Fix issue when printing 2D vectors

This patch addresses an issue with the text-based stats output which
resulted in Vector2D stats being printed without subnames in the event
that one of the dimensions was of length 1.

This patch also fixes the total printing for the 2D vector. Previously
totals were printed without explicitly stating that a total was being
printed. This has been rectified in this patch.

All regressions pass after appending ::total and the second dimension name to the places where only one item was stored (e.g. pkt_count for the toL2Bus)
