`has_one` field on show page doesn't render `Show` action, and renders parent record when it shouldnt.

[gee-forr]

Describe the bug

If I have a model (A), that has a has_one assoc to another model (B), the show page for model A renders the has_one for model B with two problems:

1. Model B does not have a Show action, so there is no way to link to the has_one assoced resource.
2. Model B renders its parent model as a belongs_to when it shouldn't - as we're already on the parent model's show page. (see screenshot)

Steps to use in the reproduction repository

• Create a model that has a has_one assoc to another model
• Specify the field in your model as has_one
• Go to your model's show page
• You will see there is no way to go from viewing your parent model to viewing the has_one assoced model.
• Additionally, the embedded has_one model renders the parent model. This could be omitted for a cleaner and simpler view, as we're already viewing the parent model.

Expected behavior & Actual behavior

• There should be a way to jump to the has_one assoced model, when on the parent model's show page.
• An embedded has_one assoc should omit its parent record.
