False positive on `comma-dangle` with `RestProperty`

[sompylasar]

What version of TypeScript are you using?
2.3.2

What version of typescript-eslint-parser are you using?
3.0.0

What code were you trying to parse?
Code is closed-source, but the gist is this:

const SomeComponent = withStyles(styles)(({
  children,
  ...props
}) => {

What did you expect to happen?
No warning for missing comma at the ...props line.

What happened?
warning Missing trailing comma comma-dangle for the ...props line.

Eslint recently disabled the trailing comma after the "RestProperty" but the parser likely generates "Property" node (based on my hacked-in logging from within the comma-dangle rule).

This warning: https://github.com/eslint/eslint/blob/70367d1a48c8c71f9fbde05da4a7a626a59967fd/lib/rules/comma-dangle.js#L266

Here's the check for "RestProperty" which seems to fail because just "Property" is there instead:

Thanks for the report.

We are using the incorrect node type. It should be ExperimentalRestProperty and we are using Property type.

@soda0289 Thanks for 868f22a ! Any chance to release this as a bugfix version?

The plan is to merge in the last fix and release 3.1, just waiting on a review.
