Test: Restrictions on Minting Licenses

[jdubpark]

Following #47 from @Ramarti, this PR enhances the previous PR with the latest main tracking.

Based on @Ramarti's note:
Previously, we assumed a policy must be set for an IPAccount to mint out licenses. However, we now consider two cases:

• If IPAccount has a policy set, ANYONE can mint a license after conditional ParameterFramework checks.
• If IPAccount doesn't have a policy set, the owner or delegate of the IPAccount is permitted to mint a license with an unattached policy. No other entity can mint a license.

Merging this will close #47 as well.

I thought we have a default "on-chain UML" as the default policy for everyone. So there should be a policy attached to every IPAsset. @Ramarti @jdubpark
