If you call GetOpenDocumentInCurrentContextWithChanges, and the
SourceText given isn't the one currently in the workspace, it forks
the solution to get the text to match. It was only forking the
active context, which meant if the feature (like completion) then tried
to look at the other linked files, it might crash because the text
is entirely in a different state. The crashes we saw in the wild are
when editing towards the end of the file and you had a delete -- it
means a span in one file is simply running past the end of one of the
linked documents.

The fix is to make sure all linked copies are updated.
