as_data_frame_matrix: "envir" argument in getS3method

[itsdalmo]

It seems like envir is not a valid argument in utils::getS3method in R version 3.2.4. Couldn't find a specific mention of when this was added to R.utils, but unless there is something wrong with my R install I suppose this warrants a version bump for the R in DESCRIPTION.

getS3method is only used on one line however, so it might be a better idea to just add an if statement for older versions of R (where envir is not an argument) and something like this:

get("as_data_frame.matrix", envir = asNamespace("tibble"))

Could submit a PR if I have the right idea here (and figure out which version of R.utils added the argument).

Probably @krlmlr should at least take a look at this because he did the original PR.

I just submitted tidyr to CRAN so we'll probably need a fix soon.

It's been introduced in R 3.3.0 (wch/r-source@9d226b4940246d12#diff-a76a25f7e4bd0d72aded7945249a3a5aR255). I'll submit a compatibility fix.
