filectx: fix annotate to not directly instantiate filectx

28a302e9225d changed basefilectx.annotate() to directly instantiate new
filectx's instead of going through self.filectx(), this breaks extensions that
replace the filectx class, and would also break future uses that would need
memfilectx's.
