[Bug] catch-error-name rule does not work with optional catch binding

[ehmicky]

The following code using the latest ES optional catch binding (supported by latest Acorn, Espree and ESLint):

try {
  throw new Error('message');
} catch {
  console.log('failed');
}

fails with the catch-error-name rule:

Cannot read property 'name' of null
TypeError: Cannot read property 'name' of null
