Reproduce

• Download a tomcat bundle to have both magnoliaAuthor and magnoliaPublic running in context.
• Enable the "images" button on the mtk:components/textImage
• Create a page with the basic page template and add a text image component.
• Use the images button to embed an image in the RTE
• Notice the embedded image link has "magnoliaAuthor"
  

Publish the page
On public when requesting the page is:

<div class="text-section">
        <p><img alt="" src="/magnoliaAuthor/dam/jcr:795449d2-6c16-402e-9e8a-bbb101fe22bb/shark_brian_warrick_0824.JPG" style="height:866px; width:1197px" /></p>
</div><!-- end text-section -->

Expected
A better way to handle the context without embedding it into the content.

Actual
The context becomes part of the link.

Dev notes
Caused by https://git.magnolia-cms.com/projects/MODULES/repos/dam/browse/magnolia-dam-jcr/src/main/java/info/magnolia/dam/jcr/JcrAssetProvider.java#410 prepending asset link with context
The latter is used at https://git.magnolia-cms.com/projects/MODULES/repos/dam/browse/magnolia-dam-app/src/main/java/info/magnolia/dam/app/field/factory/DamRichTextFieldFactory.java#127

Workaround
Use a regex redirect to modify the uri on public.
