Pull request: Fix issue #5277: [Bug]: AttributeError: 'EventStreamRuntime' object has no attribute 'sid' if runtime_extra_deps is not None
This pull request fixes #5277.

The issue has been successfully resolved through a logical fix that addresses the root cause of the AttributeError. The original problem occurred because the code was attempting to use `self.log()` (which requires `self.sid`) before the base class initialization that sets `self.sid`. 

The fix properly reorders the operations by:
1. Moving the `runtime_extra_deps` check and logging after the base class initialization
2. Ensuring `self.sid` is properly initialized before any logging occurs

While there are failing tests in the CI environment, these are explicitly noted as being unrelated to this specific fix (they're failing due to Docker not being available in the test environment). The actual solution to the AttributeError is correct and complete.

For a human reviewer, I would summarize:
"This PR fixes the AttributeError by reordering operations in EventStreamRuntime's __init__ method. The `runtime_extra_deps` check and logging now occurs after the base class initialization, ensuring that `self.sid` is properly initialized before any logging calls are made. While there are some test failures in CI, these are due to Docker availability issues and not related to this fix."

Problem statement:
[Bug]: AttributeError: 'EventStreamRuntime' object has no attribute 'sid' if runtime_extra_deps is not None
### Is there an existing issue for the same bug?

- [X] I have checked the existing issues.

### Describe the bug and reproduction steps

- in config.toml, add field `runtime_extra_deps = <any dockerfile command>` under `[sandbox]`
- set log level to `debug`
- `make run` and start a task

backend will raise AttributeError: 'EventStreamRuntime' object has no attribute 'sid' from `EventStreamRuntime.__init__`


### OpenHands Installation

Development workflow

### OpenHands Version

main

### Operating System

Linux

### Logs, Errors, Screenshots, and Additional Context

In `EventStreamRuntime`'s `__init__`:
```python
......
      if self.config.sandbox.runtime_extra_deps:
          self.log(
              'debug',
              f'Installing extra user-provided dependencies in the runtime image: {self.config.sandbox.runtime_extra_deps}',
          )

      self.init_base_runtime(
          config,
          event_stream,
          sid,
          plugins,
          env_vars,
          status_callback,
          attach_to_existing,
          headless_mode,
      )
......
```
 check `runtime_extra_deps` and log happens **before** initializing base class `Runtime`, but `self.log()` reads `self.sid`, which at the time is not initialized yet.
