semistandard 6.0.0 compliance

[Flet]

There are two new rules coming into semistandard 6.0.0:

• no-extra-semi - This rule is aimed at eliminating extra unnecessary semicolons. While not technically an error, extra semicolons can be a source of confusion when reading code.
• semi-spacing - Disallow a space before semicolons and force a space after them.

We're linting this repository as part of the test suite, and we found two linting issues related to these new rules:

  lib/reflector.js:140:3: Unnecessary semicolon.
  test/reflector.js:16:1: Unnecessary semicolon.

Would you mind fixing these? If its less trouble I'd be happy to send a PR.

If you would like to try it out on the CLI, just run npm install -g semistandard@next to install 6.0.0. I'm holding off on making it latest for a little bit.

Hey @Flet, thanks for making that change to semistandard, I think that's really sensible and those two semicolons were retarded, so that's great. :D
