testrunner: on error, color the "(case xxx)" part the same as filename

When using #testcases, the lines that read something like

  ERROR: test-split.t (case obsstore-off) output changed

get colored red and the filename gets highlighted with a brighter
red. This makes it harder to notice the "case obsstore-off" part, but
it does seem important, so let's highlight it.
