[experiment] Fix duplicate keys

we passed a seq of two seqs as :children to a v-table.
Reagent unpacks the seqs when it renders.
Between the two seqs, there are sometimes duplicate keys.

@hipitihop caught a warning for this, but I can't repro.

Wrapped each inner seq in its own v-table.
Ostensibly, this should prevent duplicate keys on child elements.

For #412
