Fixed LE radius projection

[sseraj]

Purpose

The projection to the leading edge for the LE radius constraint currently projects points to the LE and TE even though only the LE point is used. @bernardopacini found that the TE projection can sometimes fail. Following @anilyil's suggestion, I changed the projection to only project to the LE.
