Fatal error "Method name must be a string" on home page after Memcached server restart

I've got fatal error "Method name must be a string" on home page after Memcached server restart.

Error was in kApplication::BuildModuleEnv_NEW method, when attempt was made to get rewrite listener object, but he wasn't there.

I also have site domains enabled, so In-Portal tried to query all possible countries from current language (for site domain object), but actual language wasn't yet detected and such attempt resulted in "SELECT .... l_Name ...." sql without proper language id in it.

Both problems were happening by visiting home page just after caching server was restarted, so I grouped them into one task.
