[BUG] When trying to uninstall TrustyAI from a project the dashboard shows error "Could not find TrustyAI service", even though the TrustyAI service is installed

[alexcreasy]

When uninstalling TrustyAI from the dashboard settings menu, an error message is displayed saying Could not find a TrustyAI service instance in namespace: $namespace even though the service does exist

Reproducer:

• Use a dashboard build of f/mserving-metrics branch
• Create a new data science project
• Go to the settings tab
• Click 'Enable TrustyAI'
• Wait ~1 minute for the TrustyAI service to spin up (note due to a separate bug the success banner will show immediately, you still need to wait)
• Uncheck the "Enable TrustyAI" checkbox
• Confirm the deletion and click uninstall

Observed behaviour:

• Error message is displayed (See image)
• The dashboard does not make the request to delete the CR
• TrustyAI service is not uninstalled

Expected behaviour:

• The modal window should close
• A success banner should be seen in the Model Bias card
• The "Enable TrustyAI" banner should be unchecked
• The dashboard should make a request to delete the CR
• The TrustyAI service should be uninstalled
