Fix race conditions in RPC and web API multicommand methods

Multiple multicommand methods were double-awaiting tasks - first via
asyncio.gather() with return_exceptions=True, then calling .result() on
the same tasks. This caused ConnectionResetError and other exceptions
when connections were lost.

Changed to properly use the results from gather() instead of calling
.result() on completed tasks, preventing exceptions from being raised
after they were already caught.

Fixed in:
- pyasic/rpc/base.py:144 - RPC _send_split_multicommand
- pyasic/web/espminer.py:79 - ESPMiner multicommand
- pyasic/web/auradine.py:149 - Auradine multicommand
