Description

When a jcr:content node is deleted, it removes all the aliases present below that path

For example:

Let's say we have

    /
        - content
    	    - A
    	        - jcr:content
    	        - B
    	            - de_DE - has sling:alias de
    		    - en_GB - has sling:alias en
    	        - C
    		    - it_CH - has sling:alias it

If /content/A/jcr:content node is removed, It deletes all the aliases (in-memory in the MapEntries) which start with /content/A/
