Custom navigation - update 1 : Home in breadcrumb bar redirects to a different site

[BradHN1]

User Story

As a community who uses the custom navigation menu to embed ME pages into their website
I want "Home" to redirect to our main website - same as where the Home menu item redirects to, or where the Logo redirects to
So that Home is a consistent place.

The figure below shows the actions page for HarvardEnergize in canary, where they have eliminated the menu altogether and just use the logo to get back to their home site. In that case they want "Home" on the breadcrumb bar to take them to the same place.

The way this should work is that if Home is defined to point to an external site on the custom menu, then that should be where Home redirects to. Otherwise, if there is no Home on the menu, it uses the Logo redirection address to redirect to.
