JUnit XML Merge Request Widget - Test Results failed to load

Summary

When I review a merge request a junit test result should be shown in GitLab 11.2. It's failing because of "{"status_reason":"JUnit parsing failed: no implicit conversion of String into Integer"}". junit.xml generated by PHPUnit 6.5.9.

Steps to reproduce

upload artifacts:reports:junit as part of job artifacts. open a merge request.

What is the current bug behavior?

junit.xml cannot be parsed correctly.

What is the expected correct behavior?

junix.xml should be parsed correctly ;).
