Function swapFromLocalAssetIfNeededForExactOut: If _amount is 0 then no need to perform any other step in swapFromLocalAssetIfNeededForExactOut function

if (_amount == 0) {
      return (true, _amount, _asset);

_setOwner: This function can be defined as private instead of internal

The first optimisation doesn't seem to be possible because this code path is not hit unless _amount != 0. See its use in _reconcileProcessPortal for context on why.

The second optimisation is minor.
