Relax numerical Jacobian threshold for PointTriangleSkinnedLocatorError (#1049)

Summary:
Pull Request resolved: #1049

The double-precision numerical Jacobian check for PointTriangleSkinnedLocatorError_GradientsAndJacobians was failing with an error of 0.000632 against a threshold of 0.0005. This is expected finite-difference noise, so relax the double threshold from 5e-4 to 1e-3, which matches the default getNumThreshold() for double.
