Refactor call method in Assistant to streamline context handling

- Removed the asynchronous execution of method calls, allowing for direct invocation within the current thread.
- Simplified cancellation handling by eliminating the done channel, improving clarity and reducing complexity in the call method.
- Enhanced error handling by ensuring the script context is checked before method invocation.

These changes improve the maintainability and robustness of the Neo API assistant, paving the way for more efficient method execution and context management.
