Licenseguard cannot handle "*" suffix from license-checker

[brabenetz]

Problem:

Example-Dependency: [email protected]
[email protected] has no license property in package.json, but the license-checker reads the "LICENSE" file and generates the license-identifier "MIT*". See https://www.npmjs.com/package/license-checker
This will be shown with the * next to the name of the license to show that we "guessed" at it.

Proposed Solution:

Licensguard could simple truncate after the index of the "*" like in:
