Automatic export generates the same sequence number for all content initialize nodes

When the automatic export is enabled, creating new content folders will automatically add new initialize items in the hippoecm-extension module in the referred directory. However, all these initialize items get the same value (3000.3) for the hippo:sequence number. As a result, the order of nodes is not specific enough the ensure the correct initialization of the nodes. For example, the sequence numbers should ensure that parent folders are initialized before child folders (e.g. /content/documents/news should be initialized before /content/documents/news/mynewsitem is imported).
