Nested pages are not properly listed as pages to commit when displaying the pages for a list of spaces

To reproduce:

• create an AWM in XWiki 7.4 (which will have Data and Code subspaces)
• add the main space of this AWM in the list of spaces of the SVN Application configuration
• click on "list pages to commit": the pages in the subspaces Data and Code of the AWM will not be listed properly, only the direct pages (terminal) of the space will be listed . There should be a way to list also the subspaces
