fix(hmr): catch thrown errors when connecting to hmr websocket #7111

Description

This fixes #7110 by catching thrown errors in a try block and logging the error.

Note that this just prevents errors from stopping execution, rather than enabling hot reloading to continue to work, even in a degraded capacity.
To have hot reloading continue to work in these contexts, __HMR_HOSTNAME__ must be set and the WebSocket must allow cross-origin connections.
