Code view likely references old script objects after hot reload

If a script is changed as the result of a hot reload, the `Script` object needs to be re-retrieved to get its updated VM service object ID as the internal `Script` object has been replaced by the VM.

Some issues that are likely related to this are:
- Code coverage and profiler hits disappear after a hot reload
- Rendered sources are out of date after a hot reload
- Breakpoint state isn't cleared in scripts that were hot reloaded (e.g., breakpoints are displayed even though they aren't automatically reset for the new script)

Beginne damit, die Script-Suche der Code view während des Hot Reloads nachzuverfolgen und wie sie die VM service object ID erhält. Verwende die gemeldete Coverage und die Profiler-Treffer, die gerenderten Quellen und den Breakpoint-Status als Prüfpunkte; abgeschlossen ist die Aufgabe, wenn diese nach dem Hot Reload eines Scripts weiterhin korrekt sind.
