Some of the Reset* methods are named ResetTo* and some are named ResetWith*.
That seems to imply some sort of difference which simply doesn't exist. This
commit renames them to all use ResetTo* to avoid that.
Furthermore, the inconsistency in naming terminology between
ResetToURIFragmentID and ResetWithLocalRef makes it less than clear that the
latter is exactly the same as the former, but with only the fragment identifier
being specified. This commit better aligns the naming terminology for clarity.
