DeleteWithXattrs now handles a path through a scalar xattr value in the same way as a missing xattr, which matches Couchbase Server.

Document

key:    doc1
body:   {"foo":"bar"}
xattrs: _sync   = "scalar"
        _xattr1 = {"seq":1}   (some cases only)

The path _sync.rev goes through _sync, which is a string and not a JSON object.

Code

err := coll.DeleteWithXattrs(ctx, "doc1", []string{"_sync.rev"})
// or, with a present xattr:
err := coll.DeleteWithXattrs(ctx, "doc1", []string{"_sync.rev", "_xattr1"})

Results

Document state	Paths	Old result	Expected result (Couchbase Server)
Live	_sync.rev	ErrPathMismatch. Body and xattrs unchanged.	No error. Body deleted. Xattrs unchanged.
Live	_sync.rev, _xattr1	ErrPathMismatch. Body and xattrs unchanged.	No error. Body deleted. Xattrs unchanged.
Tombstone	_sync.rev	ErrPathMismatch. Xattrs unchanged.	MissingError. Xattrs unchanged.
Tombstone	_sync.rev, _xattr1	ErrPathMismatch. Xattrs unchanged.	ErrPathMismatch. Xattrs unchanged.

A failed path makes the xattr part of the delete fail. On a live document, the body delete still happens. If every path fails on a tombstone, the error is MissingError. Otherwise, it is the error for the first failed path.

TestDeleteWithXattrsPathMismatch covers each row. If a tombstone has only some of the xattrs, TestDeleteWithXattrsMissingXattr now expects ErrPathNotFound.
