Roan Kattouw ee886cd8f8 ce.MWTransclusionNode: Protect against race condition in GCN rendering
If an MWTransclusionNode is inserted, then immediately modified,
a race condition can occur where the GCN rendering arrives for the old
node, which is already detached and doesn't have a ModelHtmlDocument
any more. Protect against this happening so we don't cause a JS error
by passing null for the document parameter to ve.resolveUrl()
