`kedro-telemetry` fix failing to send telemetry when user UUID not found

[astrojuanlu]

Description

If the user UUID is malformed for some reason, telemetry data should still be send, but instead with an "anonymous" or empty UUID.

Context

How has this bug affected you? What were you trying to accomplish?

Steps to Reproduce

$ cat (python -c "from appdirs import user_config_dir as u; print(u('kedro'))")/telemetry.toml
[telemetry]
uuid = ""

Expected Result

Nothing

Actual Result

$ uv run kedro registry list

[08/23/24 18:13:57] WARNING  Failed to send data to Heap. Response code returned: 400, Response reason: Bad plugin.py:336
                             Request

[astrojuanlu]

This issue is about finding out why the Heap request fails. Several things not specifically related to it:

• Having the INFO and WARNING messages after the error make it more difficult to spot.
  • Maybe the INFO should be on top?
  • And, if the request to Heap ever fails, I'm not sure the user cares. Maybe we should make it DEBUG
• It was surprising to read "is there a pyproject.toml in your cwd?" message when there was indeed one. Maybe we could tweak the hint so it says "is there a pyproject.toml with a [tool.kedro] table there?"

[astrojuanlu]

I was quite misguided, the problem was with the user UUID and not the project UUID. I changed the body accordingly.
