Loading a clover xml breaks on classes without lines

I was having an issue with clover xml files I generated with phpunit sometimes failing to load:

[1539175884820][coverageservice]: Loading 1 file(s)
[1539175884824][lcovparser][clover-parse]: Error: Cannot read property 'forEach' of undefined
[1539175884824][lcovparser][clover-parse]: Stacktrace: TypeError: Cannot read property 'forEach' of undefined

For me this happens on cases like this, where there’s a class with no lines:

<file name="/app/Models/Scenario.php">
  <class name="App\Models\Scenario" namespace="App\Models">
    <metrics complexity="0" methods="0" coveredmethods="0" conditionals="0" coveredconditionals="0" statements="0" coveredstatements="0" elements="0" coveredelements="0"/>
  </class>
  <metrics loc="10" ncloc="10" classes="0" methods="0" coveredmethods="0" conditionals="0" coveredconditionals="0" statements="0" coveredstatements="0" elements="0" coveredelements="0"/>
</file>

I think I’ve already found the issue and made a pull request at cvrg-report/clover-json#1 to fix my issue, but I still wanted to report it here in case anyone else using this plugin is having this same issue. If the issue is fixed in clover-json I can make a pull request to update that package in here.

@koole thanks for the reminder! this will be included in the 2.3.0 release https://github.com/ryanluker/vscode-coverage-gutters/commit/c9870a1154b1545da23eecb45ab7c1cd84bf3ead

@koole FYI, I am hoping to include this fix in the 2.3.0 release (weeks away) so we will either have to use the commit hash of your fork or hopefully just increment the module version if the maintainer gets to that npm release.
