D1159: run-tests: move newline out of colorized message

REVISION SUMMARY
  The leading newline before "ERROR:" led to an incorrect lexing of the
  message and the newline got lost.
  
  The fixed formatting can be seen in the test case. The reason we
  didn't notice before was that the bad formatting just led to the loss
  of a blank line in the test. However, there are other cases where it
  would be joined with a line saying "Accept this change? [n]" or
  "Reference output has changed (run again to prompt changes)".
