Renaming destroys relative references ".SubPage.WebHome"

Renaming a page containing relative references in a display macro incorrectly converts the relative references to direct references.

Steps to reproduce:

1. Create a page:
   Sandbox.Renaming-Bug.Page.WebHome
2. Create subpages with content:
   Sandbox.Renaming-Bug.Page.FirstSubPage.WebHome
   Sandbox.Renaming-Bug.Page.SecondSubPage.WebHome
3. Include the subpages in the page using the display macro using relative references:

{{display reference=".FirstSubPage.WebHome"/}}

{{display reference=".SecondSubPage.WebHome"/}} 

1. The content of the subpages is displayed accurately in Page.
2. Rename Page to PageRenamed using Move/Rename.
3. The content of the subpages is not being displayed in PageRenamed.
4. Check the source code of PageRenamed:

{{display reference="Sandbox.Renaming-Bug.Page.FirstSubPage.FirstSubPage.WebHome"/}}

{{display reference="Sandbox.Renaming-Bug.Page.FirstSubPage.SecondSubPage.WebHome"/}}
