When one of the builds in a history has failed before any TAP data was published, the graph displayed on a project page will then not contain image map and tooltips.

To reproduce:

• Create workflow job
• Configure pipeline script as follows:

  node {
  stage "unit tests"
  sh"""#!/usr/bin/env bash
  SECONDS=`date "+%S"`
  MOD=\$((SECONDS % 2))

  if [[ \$MOD == 0 ]]; then

  cat > sample.tap <<EOF
  1..3
  ok 1 sample First ok
  ok 2 sample Second passed
  ok 3 sample This passed # SKIP error in test 2
  not ok 4 some failed test
  error message from test
  EOF
  else
  exit 1
  fi
  """
  step([
  $class : "TapPublisher",
  testResults : "**/sample.tap",
  failIfNoResults: false
  ])
  }

• Run job for a few times until failed build encounters.
• On a job page, you'll see the graph generated.
• The tooltips and image (click) map is however missing.
