Leg source and destination are mismatched when route contains trackpoint or silent waypoint

[1ec5]

When the RouteOptions contains a waypoint whose separatesLegs property is set to false, the resulting route’s legs have mismatching source and destination property values, as though the separatesLegs property were set to true.

The following code should pass DirectionsOptions.legSeparators into Array.populate(waypoints:), rather than passing in DirectionsOptions.waypoints:

mapbox-directions-swift/Sources/MapboxDirections/DirectionsResult.swift

Lines 44 to 45 in 2d9edce

	let waypoints = options.waypoints
	legs.populate(waypoints: waypoints)

This regression of #358 was introduced by #406.

This issue is even more likely to affect Map Matching API usage, because any trackpoint would be handled like a Directions API silent waypoint.

Fixed in #560.
