fix: status shown for combined instrumentation jobs

An accidental omission of the intended `omit_status=True` keyword
argument meant that for visualizations of the longest tests, where many
jobs are combined into a single bar (for performance reasons), the
status of the shortest such job was always being reported, instead of
not reporting any status like was intended (since there could be
variation amongst the combined jobs).
