REST API: The 'Accept-Language' request header is ignored when middleware service is invoked

[gorbunkov]

Environment

• Platform version: 6.10.9

Description of the bug or enhancement

If the middleware service is invoked with the standard rest api and the Accept-Language header is set in the request, then it is expected that UserSession in the service implementation will have the corresponding locale. However, it doesn't.

The problem is that REST API filter sets the locale from the Accept-Language header to the UserInvocationContext:

UserInvocationContext.setRequestScopeInfo(sessionId, locale, null, null, null);

When the middleware service is invoked after that, this value is not used.
