When creating a subwiki from template, XWikiAllGroup rights objects do not get copied

Steps to reproduce:

• Create a subwiki that will be used as a template
• Select a page of your choice (Sandbox.TestPage1 for ex) and add any rights for the local XWikiAllGroup
• Create another wiki based on this template

Result:

• The XWiki.XWikiAllGroup rights will not be present in the subwiki created from the template

Expected result:

• The rights should be there

Rights objects from the template wiki:

Creating subwiki from the template:

Rights objects from the resulting subwiki page:

Probable cause:
The order in which the pages get copied and created in the wiki creation process.
The page containing the rights objects is copied first.
Then XWiki.XWikiAllGroup page gets deleted and recreated, which causes all the rights objects for this group to be deleted as well.
