[FIX] web_editor: properly transcode `fa` alias icons

When adding a font-awesome icon to a mail template, the icon is
converted to an image once the template is saved. To do that, the
code checks all the `.fa-XXX` definitions in the stylesheets to know
which content the image have to use. The problem is that this was
not considering the font-awesome aliases. Indeed, the `fa-facebook-f`
icon was able to be used while its alias `fa-facebook` was not working.
