Loading bar has dissappeared

[muffinresearch]

The loading bar has dissappeared from the mobile site.

There's no loading bar shown when navigating or doing an action that fetches data on -dev, stage or prod.

Potentially related to the last update [1] but needs investigation.

QA: To verify you should see the blue loading bar on the top of the page when nagivating from the home page to the "Extensions" or "Themes" link on the homepage (really, anything from the homepage but just trying to make it easy to repro–there are a few links like navigating back to the homepage that won't show the loading bar because they don't make any async requests and are instant).

It's a mystery as to what caused this. Here is all that changed in the package mironov/react-redux-loading-bar@762fa36...cfb3501

While being focused on the fact that the puzzle placeholder was missing, did not observed that the loading indicator was missing too (#9904)

Verified this on AMO-dev FF53(Win 7) and observed a loading indicator in 2 colors:

• blue while going, for example, from homepage to "Extensions"
• orange while, for example, changing the language

@muffinresearch : Please let me know if the 2 colors are intended.
