Fix #127195: Changing curve mean weight/radius/tilt changes handle type

In the case of weight, tilt or radius (these dont don't change [handle]
positions), dont change the handle types.

See the doc for `BKE_nurb_handles_test` ("Use when something has changed
handle positions")

NOTE: a siilar check is done in `createTransCurveVerts`
