insert_attribute panic with full message (bevyengine#5651)

# Objective

When an invalid attribute is inserted and the LogPlugin is not enabled the full error is not printed which means makes it hard to diagnose.

## Solution

- Always print the full message in the panic.

## Notes

I originally had a separate error log because I wanted to make it clearer for users, but this is probably causing more issues than necessary.
