DXC/Commerce: Wrong type of license check performed

Description

When Commerce sites are initialized, they perform a license check before the license system has been properly initialized. The consequence is that, for Commerce sites, the license system is always initialized with a file-based license check even if it should use access-key license check.

Step to reproduce:
1) Install a commerce site using EPiServer.CMS.Core 11.3.0.
2) Deploy in DXC-S.
3) Start the site.
4) Go to edit mode.

Expected:
The site should not give a license error (given that the cloud license settings are valid).

Actual:
A license error is displayed "License.config could not be loaded".
