cli can't handle database names with space, http api can

Bug report

System info:

Connected to http://localhost:8086 version 1.3.4
InfluxDB shell version: 1.3.4
Ubuntu 16.04

Steps to reproduce:

1. create database "with space"
2. use "with space"

Expected behavior:

database "with space" created, ability to use it in cli queries

Actual behavior:

database "with space" created

use "with space"
Could not parse database name from "use "with space"".

Additional info:

HTTP api has no problems accepting data for the database, seems to be a pure cli problem. Can create and drop the database "with space" via the cli, just not use/inspect it.
