It seems that at some point (potentially with the switch to Webpack 5)
Webpack started using the full chunk name (instead of just a numeric
identifier) in `ChunkLoadError` messages. So the error messages changed
from:
```
ChunkLoadError: Loading chunk 2 failed.
```
...to:
```
ChunkLoadError: Loading chunk src_app_something_some_module_ts failed.
```
This commit updates the regex that is used to detect such errors (in
order to print ServiceWorker-related debug info) to correctly recognize
the new error message format.
