weird behavior with fixtures using count(*)

[majazaloznik]

Using the vignette example with the nycflights data, if I change the query to a simple select count(*) the saved fixture has a value of 0 instead of the actual output of the query. (It works fine with the original select statement).

I'm not sure though, I might be doing something wrong. But this is what my output looks like:

> start_db_capturing()
> fun_db()
  count
1 133004
> stop_db_capturing()
> with_mock_db(
      fun_db()
 )
  count
1     0

Sorry I didn't reply to this earlier. That does indeed seem wrong. Is it possible to re-run that with debugging on? YOu can enable that with something like set_dittodb_debug_level(3) (or really any integer over 2..). That might point to where the bug is.

And of course if you're interested in submitting a PR, I would be happy to review + provide some pointers. If not, I can try and take a stab at it myself.
