tdf#100783 Avoid infinite recursion in Content::getObject()

Browse Source 
With certain CMIS host URLs, it is possible that exception handler
in Content::getObject() will recursively call itself with the same
data (xParent from the same URL).

This patch checks if the new URL is not the same as own, to avoid
this.
