Initialize a git repository when initializing a new project from a template

[callicles]

Right now when you initialize a new moose project, we initialize a git repository at the same time.

ie

moose init test-project

Creates a `test-project` directory with files and a Git repo in it.

We don't do it when we run

moose init --template product-analytics test-project

it also creates a test-project directory but it is not initialized with a Git repository
