Remove styling for leaflet-marker-icon

[nstjean]

Addresses problem mentioned in #6969

[nstjean]

This styling was originally in rich.html.erb for the /post/ location form. The style was causing an issue with some map layers, but wasn't doing anything to the color of the marker in /post/ .

I am not understanding the codecov report. This patch affects 0% of the coverage, but it's showing project is -4.89%?

Hmm. It's possible there is a problem with it... let's try restarting it. I'll take a screenshot so we can compare once it finishes again.
