fix: catch errors when destroying invalid upgrades

Before this change, receiving an HTTP2 upgrade would make the server
crash:

> Error: read ECONNRESET
>    at TCP.onStreamRead (node:internal/stream_base_commons:217:20) {
>  errno: -104,
>  code: 'ECONNRESET',
>  syscall: 'read'
> }

This can be reproduced with Node.js v14.15.3, v16.18.1 and v18.12.1.
