ci: Make test_suite a dictionary of lists

The test_suite dictionary in 'ci/test_files_touched' used to contain
values of mixed types (both strings and lists of strings). As a result,
we were checking for the instance type before adding the value to the
alltests string.

This commit makes the following change:
  1) Changes all values in tests_suite to lists of strings, even if the
     list is only one element.
  2) Removes the isinstance check before extending the value to alltests

Resolves #322
