LPEs require movement before Reverse takes effect

Hi Inkscape developers. Hi @doctormo.

Steps to reproduce:

• open Inkscape
• create a path with an LPE (e.g. spiro, bspline)
• add a marker to one of the two ends of the path
• try to invert the path via command Reverse in the menu Path
• it seems nothing happen
• move the path and you will see the path reversed

What happened?

Nothing! The marker do not switch to the other side.

What should have happened?

The marker has to switch to the other side just after the command issue.
