v3-beta8: `ionic start` also works when already in a project directory

[janpio]

What version of the CLI are you using? Output of ionic --version

3.0.0-beta8

Short description of the problem:

When I run ionic start in a project directory it does exactly the same thing as when I am not.

What behavior are you expecting?

Small error message "You are already in a project directory. Please go somewhere else". Or "You are already in a project directory. Do you really wont to create another Ionic project here?" (if this makes sense in any case)

Steps to reproduce:

1. Install v3.0.0-beta8 CLI
2. ionic start test
3. cd test
4. ionic start test2

Post the output of ionic info below please

npm (global):

    @ionic/cli-utils : 0.0.12
    ionic            : 3.0.0-beta8

System:

    Node       : v6.10.2
    OS         : Windows 10
    Xcode      : not installed
    ios-deploy : not installed
    ios-sim    : not installed
