Delete modules with *license*

[phips28]

Hi,
modclean deletes modules with license in the name.
This breaks our deployment step.

      └─┬ validate-npm-package-license@3.0.1
        └─┬ spdx-correct@1.0.2
          └── spdx-license-ids@1.2.2

Can you fix this please in the pattern?

@phips28 I made some changes to the patterns for version 1.1.0. Hopefully this fixes the issues.

Let me know if you are still seeing any issues!
