Fetching License type sometimes fails, although it's displayed on Github

First of all, thanks for creating this great lib! 👏🏼

Just wanted to mention, that some repositories do have the license type specified, for example
AWS has Apache 2.0:

The issue probably happens because there's like a list of licenses, and the first item appears to be "Unknown", but then the second correct one is Apache.
Maybe we can Ignore the "Unknown" license type and grab the other one?
