chore(deps): COMPASS-4191: Switch to namespaced fork of triejs on npm (#62)

[COMPASS-4191](https://jira.mongodb.org/browse/COMPASS-4191) notes:

> vscode `npm run package` fails like so:
https://dev.azure.com/team-compass/vscode/_build/results?buildId=746&view=logs&j=291b3e6c-60a9-5f30-6b17-b27c7388dcd0&t=73e02479-b06a-558b-66de-a6177ecb9da0&l=63
> 
> ```
> ERROR  Command failed: npm list --production --parseable --depth=99999 --loglevel=error
> npm ERR! missing: triejs@github:rueckstiess/triejs, required by mongodb-index-model@2.5.0
> ```

The [changes to triejs are minimal](pthurlow/triejs@master...rueckstiess:master) in the fork so I made [`@mongodb-js/triejs`](https://npm.im/@mongodb-js/triejs) to remove the `git://` dep complexity from our build toolchain.

While I'm in here, I've also done dependency updates, fixed tests, and added additional debugging for Compass' sake.

* chore: Update dependencies

```

* chore: Fixes for dependency updates

- `async@3` tasks in an `auto()` chain have callback and data args flipped from `async@1.5`
- `mongodb` prints warning unless `useUnifiedTopology: true` in `connect()`
- `mocha.opts` file is deprecated
- bring travis and npmignore templates up to date
