Bug 1778202 - show error message in failure even if it is supposed to be classified with a single tracking bug (#7477)

Bug 1757222 removed the error message from failure lines if they are supposed to
get classified with bugs which track all failures for a test (single tracking
bug). The error message contains valuable information (e.g. it can indicate if
the issue is a permanent failure) and should be shown.
