Parents with "/" in the name are duplicated by the nested pages migrator

[snazare]

Steps to reproduce:

1. Find a space where there are parent pages with "/" in the name
2. Run the Confluence migrator on said space

NOTE: Starting with xwiki 13.x the "/" in the name should be automatically removed. Therefore if you are using a recent version, the fix in step 5 should not be needed. I am testing on XWiki 14.4.6 cloud and I see no difference whether I run the step 5 fix or not.

Expected result step 6:
The parent page with "/" in the name is moved in the correct location, along with its children.

Actual result step 6:
An empty parent page with "/" in the title and in the name stays in root, but has the correct children.
Another parent page with "/" in the title but not in the name appears in the correct location, with the correct content but no children.

With invalid parents fix at step 5:

Without invalid parents fix at step 5:

I reproduced the issue on a fresh XWiki 14.4.6 instance using the Nested Pages Migrator Application version 0.9.0 without going through the confluence migrator, see screenshot below. So, it is possible that the issue is a Nested Pages Migrator issue.

According to The Nested Pages Migrator Documentation the migration is based on the parent/child relationships, so, I verified the imported flat pages in step 4 in to make sure that the parent/child relationships are correctly set. I find the following results concerning the pages with slash in their name which are not correctly migrated :

Title	Page	Parent	Is parent correct ?
Parent / page with slash	NOV.Parent page with slash	NOV.November	YES
Children under slash 1	NOV.Children under slash 1	NOV.Parent / page with slash	NO
Children under slash 1	NOV.Children under slash 1	NOV.Parent / page with slash	NO

Based on the table above we can see that the parent of the 2 children pages is incorrect, the parent is Parent / page with slash instead of NOV.Parent page with slash, so, the duplication of pages and the wrong location obtained by the nested pages migrator is correct because it reflects the parent/child relationships of the imported pages.

The next step is to investigate why the parent/child relationships of the imported pages (step 4) are incorrect for pages with slash (/) on their names.

After investigation I find that the issue is caused by a bug on the XWiki Confluence XML importer, I opened a ticket on the XWiki confluence JIRA project, see https://jira.xwiki.org/browse/CONFLUENCE-113.
