bug in report.html template
originally reported as https://github.com/inorton/junit2html/issues/48
> In the main template file report.html two different syntax are used to asses if a test case has failures
>
> works:
>
> `{% if test.failed() %}`
>
> always true:
>
> `{% if test.failed %}`
>
> It seems second variant will return true even if no failures, or the branch statement be disregarded,
> because for me this caused elements associated with failures to be printed into the output file,
> despite no failures in the test. Adding the brackets fixed it.
