Expected Behavior

When creating a new project with dune init project foo, the default dune file for the test folder could look like:

(test
 (name test_foo))

Actual Behavior

When creating a new project with dune init project foo, the default dune file for the test folder will look like:

(test
 (name foo))

This makes it really confusing to new people when they try and add their foo library as a library dependency in this dune file.

Reproduction
