fix(javascript): keep unselected sources out of cancellation failures

With source_paths, the analysis loop checked cancellation before it
recognized an outside-analysis-scope file. Cancellation arriving after the
last selected source therefore recorded the next unselected file as a
cancelled analysis failure, and the completion loop skipped it as already
analyzed.

Give out-of-selection classification one owner, used by the loop, the
interruption handler and the completion loop. The cancellation is still
reported as the interruption.
