Example for gauge refactor is inconsistent with example output

[AMWatty]

Executing the example code for refactor doesn't result in the example output, due to typo (omitting the word 'id' in the example line).

output will be:

• create user "john" with "123" and last name "watson"
• create user "mark" with "345" and last name "watson"

To address the problem, I would suggest changing the example refactor line to:
gauge refactor "create user <name> with id <id>" "create user <name> with id <id> and last name <watson>"
