recipetool: create: fix falling back to declared license for npm packages

Fix two problems falling back to the "license" field from package.json
when no license file is present:
1) The function that was supposed to return the license field value was
   always explicitly returning None, and this was never noticed (because
   the test cases never exercised the fallback as they provided license
   files for each module).
2) Fix the main package not falling back because it had a default of an
   empty list, which evaluates to '' instead of 'Unknown'.
