Metrics reporting with OutputModel while in offline mode results in an error

[GuillaumeRoy33]

Describe the bug

Calling one of the reporting methods of the OutputModel class after its task has been set offline results in an error. The method crashes with the following error:

File "/home/(...)/.venv/lib/python3.9/site-packages/clearml/backend_interface/metrics/interface.py", line 62, in __init__
    offline_folder = Path(task.get_offline_mode_folder())
AttributeError: 'OutputModel' object has no attribute 'get_offline_mode_folder'

To reproduce

Here is a code bit reproducing this error:

Task.set_offline(offline_mode=True)
task = Task.init(
    project_name="test",
)
output_model = OutputModel(task=Task.current_task())
output_model.report_scalar(title="Some title", series="Some series", value=1.0, iteration=5)

Expected behaviour

I would have expected the OutputModel class to either log the metrics in its local file system or, if this is not possible, raise an error earlier when it was initialized with an offline task.
