MySQL span name truncated to "/*" with inline comments in query

**Describe the bug**

When using inline comments in MySQL queries, the APM span name only shows /* instead of the actual SQL query. This makes it difficult to identify and monitor specific database operations in the APM UI.

**To Reproduce**

Steps to reproduce the behavior:
1. Configure Elastic APM Node.js agent and set up MySQL connection
2. Execute a query with inline comment like:
```
/* GetUserProfile */ SELECT * FROM users WHERE id = 1
```
3. Check the transaction in APM UI
4. Transaction name is shown generically as '/* ', ignoring the inline comment 'SELECT * FROM users'
**Expected behavior**

The span name should display the actual SQL query (e.g., "SELECT * FROM users") rather than just showing /*. This would provide proper visibility into the database operations being performed and make it easier to monitor and debug database queries.

**Environment (please complete the following information)**

- OS: macOS 14.3
- Node.js version: 22.7.0
- APM Server version: 8.12.0
- Agent version: 4.11.0

**How are you starting the agent? (please tick one of the boxes)**

- [ ] Calling `agent.start()` directly (e.g. `require('elastic-apm-node').start(...)`)
- [x] Requiring `elastic-apm-node/start` from within the source code
- [ ] Starting node with `-r elastic-apm-node/start`
