ioPack should have common.licenseInformation instead of common.license

[foxriver76]

• and license field only in pack json
• see added enhanced adapter license info to schema and types ioBroker.js-controller#2591

Please release this change note before

• standard ioBroker github tests accept the new field
• repository checker can handle the new field
• devPortal can handle the new field

othwise we would have to explain why a newly created adapter fails our own tests

[mcm1957]

If this testing is adapted, please check if this one ioBroker/testing#577 can be done too. Its a little bit nasty to explicit remove the tests at code from files for wwwOnly adapters.
