Connection override fix

[singankit]

Description

Connection override does not work when running a flow after first run.

flow = load_flow(...)

flow.context.connections = {
            "query_llm": {
                "connection": AzureOpenAIConnection(
                    api_base=model_config.api_base,
                    api_key=model_config.api_key,
                    api_version=model_config.api_version,
                    api_type="azure"
                ),
                "deployment_name": deployment_name,
            }

flow(...) # This work
flow(....) # This fails
