bst init does not respect --element-path option
Reproduction steps: Run bst init --element-path my-element-path
in an empty directory.
Expected output: project.conf is generated that has element-path set to "my-element-path" and a directory named "my-element-path" is created.
Actual output: project.conf is generated that has element-path set to "my-element-path" BUT a directory named "my-element-path" is not created. Instead a directory named "elements" is created.
