Calls to as.data.frame() seem to be returning confusing column classes.

[SimonGoring]

The as.data.frame() call is casting certain columns to non-intuitive column types. This causes problems with using functions like dplyr::inner_join() on tables.

library(neotoma2)
> ds <- get_datasets(1:10)
> df <- as.data.frame(ds)
> class(df$siteid)
[1] "character"

Expected

The ID columns should be integers. Other columns should be properly typed/classed.

Note that this actually conflicts with the use of UUIDs in the set_*() functions, which add unique string/character identifiers to records to maintain some form of unique value for object IDs.
