Subject: [PATCH] Pin Travis to Node v9 to avoid v10 failures

v10 fails currently: https://travis-ci.org/slevithan/xregexp/builds/370310563#L510-L528

```
Failures:
1) XRegExp() supports new regex syntax: named capture should throw an exception if characters other than A-Z, a-z, 0-9, $, and _ are used in capture names
  Message:
    Expected function to throw an Error.
  Stack:
