[Bug]: Multiple REST API requests fail when "set-session-context": true

### What happened?

When requesting for multiple api requests when session context is "set-session-context": true.
This is for using DB Type: DWSQL for using against Fabric SQL endpoints.

It causes the following api response:

{
"error": {
"code": "DatabaseOperationFailed",
"message": "Cannot set key 'aud' in the session context. The key has been set as read_only for this session.",
"status": 500
}
}

I am assuming the session is being sticky and not starting new sessions for each call.
For some reason it may be caching the session when "set-session-context": true, but from my understanding that should default to false.

### Code of Conduct

- [X] I agree to follow this project's Code of Conduct

Start by tracing the REST request through Azure.DataApiBuilder.Service.Controllers.RestController and Azure.DataApiBuilder.Core.Resolvers.QueryExecutor.ExecuteQueryAgainstDbAsync, using the supplied session-context configuration and error log. Reproduce multiple requests against Azure SQL and determine why the 'aud' key is set read-only more than once; done means repeated requests no longer return this 500 error.
