_vj_collection.sass: Remove z-index from .has-error:before
Created by: teddywing
When an error occurred when modifying a time in a journey pattern, it would be surrounded by a red box. The trouble is, you wouldn't be able to click inside that box to focus the inputs and change times once the box was added.
The problem happens on this page: http://stif-boiv.dev:3000/referentials/4/lines/158/routes/1/vehicle_journeys
This was due to the z-index placing the box on a layer closer to the front than the inputs, eating click events and preventing them from being clicked on.
Originally I thought about using pointer-events: none; but according
to http://caniuse.com/#search=pointer-events it isn't supported in
IE < 11. Eliminated the z-index instead which has the same effect and
doesn't appear to cause any visual problems, at least on the page I
mentioned. Only tested in Opera TBH.

Here's what the problem looks like:
