Count doesn't return a number when used in subquery

[Wardormeur]

Hi,
First of all, thanks a lot for this library :)
When querying a count through a subquery (as shown here : http://vincit.github.io/objection.js/#getting-count-of-relations), the query results returns a string rather than a number
The corresponding tests are the following, which I would consider to be an unexpected result.

objection.js/tests/integration/find.js

Line 899 in f398479

it('should work in select', () => {

If this is related to #744 and how $relatedQuery is supposed to evolve, please feel free to close this issue :)
Thanks again,
W.

Apologies, it seems to be unrelated to objectionjs.
