Describe the bug

In version 3.2.0 svgo fails on certain files with the following error when using the convertPathData plugin. The issue does not occur in v3.1.0 and earlier.

/tmp/node_modules/svgo/plugins/convertPathData.js:1160
  return [2 * base[0] - controlPoint[0], 2 * base[1] - controlPoint[1]];
                                    ^

  originalSvg,
  {
    plugins: ['convertPathData']
  }
)

I'll see if I can get a fix in for this today. (if I could assign myself to it I would but I don't have the perms.)
