A putFootnotes macro in a list item breaks the footnotes of the page

When the putFootnotes macro is placed in a list item or a table cell, it fails with "The [putFootnotes] macro is a standalone macro and it cannot be used inline.", and the footnotes of the whole page break with it: since the page has a putFootnotes macro, the footnote macro does not add the list of footnotes at the end of the page, and the text of each footnote is rendered inside the sentence, with no number and no link.

Steps to reproduce

1. Edit a page in the wiki editor with this content:

   A{{footnote}}N1{{/footnote}}.
   
   * one
   * {{putFootnotes/}}
   

2. View the page.

• Expected: a footnote number after "A" and the list of footnotes, either where putFootnotes is or at the end of the page.
• Actual: "AN1.", the footnote text glued to the sentence, then the standalone error in the list.

The fix is in FootnoteMacro.java and PutFootnotesMacro.java: a putFootnotes macro that fails should not prevent the footnotes from being listed, for example by adding them at the end of the page as when there is no putFootnotes macro. XWIKI-23501 covers the standalone error itself.
