Update to RSQlite causes warnings

[eliotmcintire]

In saveToLocalRepo, createLocalRepo and likely others: many new warnings appearing, which appear to have come with RSQLite 2.0 which is now on CRAN.

a <- 1
repo <- tempdir()
archivist::createLocalRepo(repo)
archivist::saveToLocalRepo(a, repoDir = repo)

Warning messages:
1: In rsqlite_fetch(res@ptr, n = n) :
  Don't need to call dbFetch() for statements, only for queries
