Mohammad Hassan f7382561cf Do not fail to disable a component with an unimportable path ... `get_component_priority_dict_with_base()` normalizes every key of a component priority dictionary by calling `load_object()` on it, including keys whose value is `None`, i.e. components the user is disabling. `normalize_key()` only guarded against `(NameError, TypeError, ValueError)`, the three exceptions `load_object()` raises itself, but not against the `ImportError` raised by the `import_module()` call it makes. A stale entry disabling a component whose module no longer exists, e.g. `{"scrapy.webservice.WebService": None}`, therefore aborted settings resolution with `ModuleNotFoundError` instead of being ignored. Add `ImportError` to the guard so that an unimportable key falls back to its raw string form. Since its value is `None`, it is then dropped by the existing `if v is not None` filter, and disabling by import path keeps working. Enabled components with an unimportable path are unaffected: `MiddlewareManager.from_crawler()` calls `load_object()` on them again and still fails there.
