Update make_live_ocean_files re: single filepath

`salishsea_tools.LiveOcean_BCs.create_LiveOcean_TS_BCs()` returns a single
 filepath not a list of filepaths. As a result of this change, the related
 logging message and checklist assignment have been updated and corresponding
 test cases have been adjusted as well.
