apigee_nonmint_company: Company invitation entity label not set properly

[kbielawiec]

While using the apigee_nonmint_company along side the Drupal Audit Log module, you are unable to send/accept company invitations. It appears to be because the audit log module is unable to properly load the entity type of the invitation (see below).

Steps to reproduce:

1. Start with a stock developer portal
2. Install and enable apigee_nonmint_company and audit_log(https://www.drupal.org/project/audit_log) modules
3. Create a new company
4. Invite a developer to newly created company
5. Receive fatal error:
