enable overriding favicon from Helmet component

[giuliaghisini]

if i want to load favicon differently than loading it from /public folder, i have to override the /helpers/Html.js component because favicon is statically linked here and i'm not able to override it by Helmet component.

no.. here we need to set favicon from an api response, not from a static folder. Otherwise, i thin for all this 3 issues the solution is the same.. maybe the solutions are two:

1. move the markup of favicon inside a specific component that will be overridable
2. make Helmet component able to set/render the favicon markup
