deleteDocument() : Error : Statement to be removed is not on store

[bourgeoa]

For example trying to edit with the source-pane https://bourgeoa.solidcommunity.net:8443/public/

Statement to be removed is not on store: _:n185 <http://www.w3.org/2007/ont/link#status> _:186 .

_:186 object is the term.value of Collection

The issue occurs only at the st.object being an (object) Collection in the metadata status part.
It looks like if st.object do not get the Collection elements.

removeMatches() calls removeMany() that calls remove() that fails on that object Collection.

This must be better explained :
This is the serialization of the metadata for https://bob.localhost:8443/profile/card

The issue is with the last object Collection

              ( "[0:16:35.259] N3 parsed: 13 triples in 26 lines."

  ].

@angelo @timbl
I have prepared 2 working solutions (tested on NSS)

• PR removeMetadata #633 that remove the use of removeMatches in removeMetadata
• PR Issue#631bis #636 that remove the use of Collection in fetcher to create metadata

@timbl
The collection issue on store.removeMetadata() is not resolved
One way to HACK the issue is to replace the status collection with simple triples

A hack has been implemented in source-pane to move the error to a console.log()
