[BUG] Bias metric chart selector shows a selected, non-existent chart when metrics are deleted by direct call to the TrustyAI API

[alexcreasy]

Reproducer:

• Create a bias metric configs
• navigate to the model bias tab
• Select that chart using the selector
• Delete that bias metric by making a call against the TrustyAI API directly
• Refresh the page

Observed outcome:

• See the image, you can see that the "Loan acceptance" chart is selected, even though it no longer exists, the selector is disabled and the "Bias metrics not configured" empty state is visible.

Expected outcome:

• No metrics should be selected

Additional information:
This is due to a stale entry in the browser storage. When the metric config is deleted via the dashboard, the entry is removed from the browser storage at the same time, so this bug is not observed when only using the dashboard. The component will need to check if any selected metrics exist on the trustyai side when it mounts and clear them from the browser storage if they do not.
