Tests pages is very irresponsive

[uillianluiz]

In a job, go to the Tests tab:

• Sometimes, it won't show the list of tests. It will only show if you click in a header column so that it will trigger the sorting.
• Then, if you click in a test to get more information it will display an empty page sometimes. It used to work fine before.
• Also, if you copy the link of a specific test, it will always display an empty page with error: Cannot read property 'duration' of null

Issue 1, I can reproduce it
For issue 2, this may be a performance issue.
For issue 3, I got an empty page, too, but no error msg.

I will look into those issues.

Thanks for reporting

Issued 2 is fixed.
