Fix sequence sometimes not turning into a map (#450)

Browse Source 
Previously, just referencing the next element in the sequence (and so constructing it, as an undefined element) would allow you to skip defining an element without turning the sequence into a map. E.g:

node[0] = "foo"; // sequence of size 1
node[1]; // sequence of size 1, with an undefined element at 1
node[2] = "bar"; // FIX: should be map of size 2 (since there's no element at index 1)
