enabled multiple routes for one controller

enabled multiple routes for one controller.

solve my own issue :
https://github.com/angular/angular.js/issues/9041

Multiple routes can be used:

for abbreviation.

>.when(['/user/login, '/login''],

for same meaning.

>.when(['/user/search, '/user/find', '/user/query'],

for redirection
>.when(['/user/search, '/user/find', '/user/query'],
Shouldn't we be using `isArray()` instead ?
