Fix generic signature problems identified with new R-devel

[kylebaron]

Summary

CRAN has come up with some methods where the signature does not match the generic. This has been there for a long time and I guess R-devel changed a bit to detect this; it isn't there in R-release or R-devel up to a couple of days ago.

@kyleam - I'm not worried about the compile() method. But I really want to be able to have an as_tibble() method for the simulation output class. I had the signature right at some point but the generic changed and that caused the problems.

I'm heading toward just getting the methods matched up with the generics and sending that back. That seemed to fix the issue when testing R-devel from yesterday. Wondering about your thoughts on safe / sustainable approach going forward?

Reproduce check issue on 1.0.8

I've only been able to reproduce on (very) recent R-devel.
