Title: fix eslint warnings

While working on another PR, I noticed these warnings and thought it would be better to fix separately.

Before:

```
$ npm test

> underscore@1.7.0 test /Users/max/Sites/underscore
> phantomjs test/vendor/runner.js test/index.html?noglobals=true && eslint underscore.js test/*.js test/vendor/runner.js

Took 6057ms to run 1119 tests. 1119 passed, 0 failed.

underscore.js
886:21 warning Gratuitous parentheses around expression no-extra-parens
1121:14 warning Gratuitous parentheses around expression no-extra-parens

test/collections.js
596:10 warning ['true'] is better written in dot notation dot-notation
597:10 warning ['false'] is better written in dot notation dot-notation
614:10 warning ['true'] is better written in dot notation dot-notation
615:10 warning ['false'] is better written in dot notation dot-notation

✖ 6 problems
```

After:

```
$ npm test

> underscore@1.7.0 test /Users/max/Sites/underscore
> phantomjs test/vendor/runner.js test/index.html?noglobals=true && eslint underscore.js test/*.js test/vendor/runner.js
