fixed reference rds

[finlaycampbell]

See Issue #104 - This looks like previously buggy behaviour that was fixed in the update. The command z[k = nocoords] should only be subsetting columns, but the saved, subsetted reference linelist has 12 rows whereas the original linelist has 13. In the current version both the pre-subsetted and post-subsetted linelists have 13 rows. I've overwritten rds/z.rds with the new output, as this gives the expect output.

Thoughts @zkamvar? Would be nice to have everything up and running for the Bogota workshop.

I don't think this is the appropriate solution to fix #104 for a couple of reasons:

1. If you look back and check out the files from the history (https://github.com/reconhub/epicontacts/commits/16518beb06bfd467fc517e60b75ae8a833ef195d/tests/testthat/rds/z.rds), they all have 12 rows in the tibble (whereas the current one has 13 where the contact information is completely blank.

2. The current output is not well-formatted. Dates are numeric values and there is an extra id.1 column.

I think what needs to happen here is a re-think of what these tests are trying to accomplish and what the output should be. If we merge this PR, we are no longer testing for the truth, but rather just testing so that the tests pass.
