Fix js issue when displaying stacktraces in report

[f-lolom]

Hi everyone,

everything is in the title : the JS in TestItem.js is broken. The following error occurs in the JS console when opening a "test details" page:

Uncaught TypeError: Cannot read property 'length' of undefined
    at t.value (app.min.js:25)
    at app.min.js:97
    at s (app.min.js:97)
    at h._renderValidatedComponentWithoutOwnerOrContext (app.min.js:97)
    at h._renderValidatedComponent (app.min.js:97)
    at h.performInitialMount (app.min.js:97)
    at h.mountComponent (app.min.js:97)
    at Object.mountComponent (app.min.js:6)
    at g.mountChildren (app.min.js:97)
    at g._createInitialChildren (app.min.js:97)

Concretely, this error was preventing the "title" and the "screenshot" section to be displayed to the user.

The bug was introduced by this commit : b0c12ea

@artem-zinnatullin @yunikkk @ming13 Can you 👀 when you have time? This one-line fix would help us out a lot.

@f-lolom I don't suppose you'd be willing to rebase this PR and issue a new version of your own lib to capture this one more-recent commit 2ff3f57
