Invalid time in JUnit XML reports for ignored tests

[kostrse]

If test is ignored:

ignore should "foo bar" in {
  ???
}

then generated XML report has -0.001 time value:

<testcase classname="com.foo.bar" name="Foo bar should foo bar" time="-0.001">
  <skipped/>
</testcase>

In my experience, it breaks Azure Pipelines (VSTS Build) unit tests UI, but potentially may confuse any tool attempting to parse the test execution time.
