Check that the tests don't change the global state

[IndrajeetPatil]

Tests shouldn't change the R landscape, and testthat can't always do this clean-up for you. So we can check ourselves that we are writing self-contained tests.

To make sure that the tests aren't changing the global state, add the following to tests/testthat/helper-state.R:

testthat::set_state_inspector(function() {
  list(
    attached = search(),
    connections = nrow(showConnections()),
    cwd = getwd(),
    envvars = Sys.getenv(),
    libpaths = .libPaths(),
    locale = Sys.getlocale(),
    options = .Options,
    packages = .packages(all.available = TRUE),
    NULL
  )
})

If a test is changing the global state, it will produce warnings and the check-test-warnings workflow will fail.

To know more about how set_state_inspector() works, read the package docs.
