Call setup_logging() in FunctionHandler.initialize() for WASM handler

Without this, the accel status log messages ("Using accelerated C
call_function_accel loop" / "Using pure Python call_function loop")
are silently dropped because no logging handler is configured in the
WASM handler path. setup_logging() was only called from __main__.py
(collocated server CLI).
