ToC macro with scope=local indents the ToC items to match the level of the current section

Consider the following XWiki 2.0 content:

= S1 =

== S1.1 ==

{{toc scope="local"/}}

=== S1.1.1 ===

==== S1.1.1.1 ====

=== S1.1.2 ===

== S1.2 ==

The ToC macro generates:

*
** S1.1.1
*** S1.1.1.1
** S1.1.2

which means that the level of each list item matches the level of the corresponding section (ToC macro has start=2 by default). While this is good for scope=page, for scope=local the list items don't have to be indented: their level should be relative to the level of the current section:

* S1.1.1
** S1.1.1.1
* S1.1.2
