After upgrading ro Commerce Azure, redundant blob and event added to Commerce Manager web.config file

Description

Precondition: An old Commerce site (12.17.0) which already has Commerce Azure

Steps to reproduce

1. Upgrade the Commerce site with a Commerce Azure package (for a Commerce site and a Commerce Manager site).
2. View the web.config and episerverframework.config files.

Expected:
Should not add a blob and an event to <Episerver.framework> in the web.config of the Commerce Manager site because they were already added to episerverframework.config when installing the old version.

Actual:
Auto added a blob and an event to episerver.framework in web.config of a Commerce Manager site. So, it might be a lost connection to a blob which was already configured in the episerverframework.config file.
