Describe the current, buggy behavior

If in a Theme Header (style.css) the License is not added, when I generate the POT file, I see the This file is distributed under the .

Describe how other contributors can replicate this bug

Scenario: Wrong license information is displayed for the theme
  Given an empty foo-theme directory
  And a foo-theme/style.css file:
    """
    /*
    Theme Name: Foo Theme
    */
    """

  When I run `wp i18n make-pot foo-theme foo-theme.pot`
  Then the foo-theme.pot file should contain:
    """
    # This file is distributed under the .
    """

Describe what you would expect as the correct outcome

To see the This file is distributed under the same license as the X theme.
