Add automated test for "Convert a Terminal Document to a Nested Document"

The manual test is here: Convert a Terminal Document to a Nested Document.

The test verifies if renaming a terminal page into a nested page works properly.

Ilie Andriuta: Hi! Continuing the manual tests migration, there is a test about checking if renaming a terminal page into a nested page works properly: https://test.xwiki.org/xwiki/bin/view/Nested%20Spaces/Convert%20a%20Terminal%20Document%20to%20a%20Nested%20Document%20. I've checked: https://github.com/xwiki/xwiki-platform/blob/3c5ba57d35d5d4fa3fc997b25c853c7172e4b3e3/xwiki-platform-core/xwiki-platform-flamingo/xwiki-platform-flamingo-skin/xwiki-platform-flamingo-skin-test/xwiki-platform-flamingo-skin-test-docker/src/test/it/org/xwiki/flamingo/test/docker/RenamePageIT.java, but it seems I didn't find automated tests for it (I've noticed an automated test for converting nested pages into terminal, though). Can you please confirm whether the automated test exists for it or not and maybe providing the link to it?

Thanks!

Thomas: It does indeed seems like we only have WebHome -> final automated test, but not the other way.

Ilie Andriuta: thanks, Thomas! I will create a task for it
