Fix typo

I got the following error when calling getDocuments:

	node_modules\ravendb\lib\database.js:57
	      return this.api.getQueryiesUrl();
			      ^
	TypeError: Object #<Api> has no method 'getQueryiesUrl'
	    at Database.getQueriesUrl (d:\reporting\node_modules\ravendb\lib\database.js
	:57:23)
