erp5_core: reindex recursively only if indexable children type exists in Base_reindexObjectSecurity.

This is important especially for SyncML Subscription having tons of SyncML Signatures that is non-indexable.

Note: first I tried the change in the restricted python only like :

+      type_tool.getPortalTypeClass(portal_type_name).isIndexable():
     reindex = context.recursiveReindexObject
     break
 else:

but I got the following exception :
