exception during autocomplete: "Cannot call \"floatApprox\" on prototype of \"NumberLong\""

Basically fails any tab complete on a NumberLong object.

e.g.

$ ./mongo --nodb
MongoDB shell version v3.3.10-669-g731632e
> var x = new NumberLong()

now type x and then hit tab

> x.exception during autocomplete: "Cannot call \"floatApprox\" on prototype of \"NumberLong\""

Seems not to happen on 3.2
