v 1.9.0 released today error with data.table 1.12.0

Hi,
Rdatatable/data.table#3149 is fixed in data.table 1.12.0 so checking the old behaviour will fail here when data.table 1.12.0 goes to CRAN : https://github.com/mllg/checkmate/blob/master/tests/testthat/test_checkDataTable.R#L66.

* checking tests ... ERROR
  Running ‘test-all.R’
Running the tests in ‘tests/test-all.R’ failed.
Complete output:

Please can you update either now or after data.table 1.12.0 is on CRAN is fine too.
Thanks, Matt

Whoops, these lines should not have been released. Fixed in master, and ready to release a new version to CRAN as soon as needed.
