create-waku confuses the target dir

[tylersayshi]

The issue happens when a project is created named waku-project and then any other project is attempted to be made in the same directory.

you can test this by:

1. make a project with the default name in a directory
2. make a new project with a new name in that same directory as a sibling/ this will register as a duplicate of waku-project but then go in the correct new name folder

Also, if a project exists named foo and another is attempted to be made also named foo the duplicate will not be detected.

It would be nice if we could break the prompts into steps instead of the single list api which is done by prompts. We've discussed changing before, but I think this issue with the side effect for targetDir which does not work is motivation for considering a different CLI library.
