Fragments are stripped from links to content

Problem/Motivation

It's currently not possible to save a link to a piece of content that has a fragment because normalizeHref
returns the entity: style href if the original href has an entity context.

Steps to reproduce

1. Create a piece of content with an alias /foo
2. Create another piece of content with a link in a wysiwyg field linking too /foo#bar
3. Save the content and notice the Linky created will be linking directly to the content and the fragment is lost.

Proposed resolution

As per the MR - we can simply detect the fragment and return it as part of the href.
