Bug 21536: t/Koha_ExternalContent_RecordedBooks.t skips more tests than scheduled

t/Koha_ExternalContent_RecordedBooks.t skips more tests than scheduled
if WebService::ILS is not available.

Test plan:
- have a system without Webservice::ILS available
- in koha-shell, do
  prove t/Koha_ExternalContent_RecordedBooks.t
- tests should be skipped and tests count as "passed"
