An ITextView can have multiple ITextBuffer instances associated with it. When looking for the main ITextDocument associated with an ITextView it should always be done through the DocumentBuffer. The previous code was using ITextView::TextBuffer which is equivalent to the EditBuffer. The reason this worked in standard files (like a .cs) is that the EditBuffer and DocumentBuffer are the same value. In razor files the view is much more complex and the EditBuffer is actually a rather complicated projection buffer (instance of IProjectionBuffer). Hence it had no associated document. closes #21
