ESLint Default Formatter Don't Work During Watch

[chriserwin]

Environment

• Node Version: 6.11.1
• Eslint-Watch Version: 3.1.2
• Eslint Version: 4.3.0

Basic Description of the problem

When trying to use one of the default ESLint formatters while using the watch (-w) option, an error is returned even though the formatter appears to work.

How to reproduce it

1. Command: esw -w -f table dir/**

@chriserwin Has this been solved with the latest release? I wrote some integration tests to ensure that the CLI can find eslint's table formatter.
