OpenAPI: generator adds prefix to name property of message

### I tried this:

I configured the generator to add a prefix using the new extension from 7.4.5 to prefix the **id** of the message to avoid conflicts because of identical operation ids in different OpenAPI spec files. I used the service id as prefix (through prefixWithServiceId) and an explicit prefix. The issue occurs in both cases.

### This happened:

The prefix was added to the id (which is what I expected), but in addition it was also added to the name of the message, which makes the prefix visible in the catalog treeview and pages, which is undesired. In addition, I got numerous orphaned messages which didn't exist before I added the prefix.

### I expected this:

I expected the prefix in front of the **id**, not the **name** property of the message. For the AsyncAPI plugin this is working correctly.

### Is there a workaround?

None than removing the prefix configuration entirely and accepting the aliasing of messages because of identical operation ids.

### Anything else?

I think it's important to mention that this works correctly for the AsyncAPI plugin.
