Bug 1018321 - Create url to one and done profile page based on username or name

Two things:

1. You're putting two `"`s next to eachother here instead of escaping them, which is what you want to do.
2. It's generally a bad idea to include IDs or classnames in translated strings in case you change the ID. To handle this, usually we give the outer tag (in this case the `h1`) the class and just use a `<span>` within the translated string, as it's much less likely to change where the `span` is.
