Previously, all asset-groups from `ngsw-config.json` were processed in parallel. For each asset-group, we retrieved all files for the current build, filtered out files that were already matched by other asset-groups, determined which of the remaining files belonged to the current asset-group and generated entries for the `ngsw.json` manifest. This process was susceptible to race conditions when there were files that would be matched by multiple asset-groups. This made the generation of the `ngsw.json` manifest non-deterministic and violated the rule that each file would belong to the first asset-group that matched it (based on the asset-groups' order of appearance in `ngsw-config.json`), thus leading to broken ServiceWorker behavior. This commit fixes it by ensuring that the generation process is deterministic and that asset-groups are processed in the proper order. NOTE 1: The generation process has been broken since the beginning, but we have only noticed this recently. This is possibly related to the CLI's switching from a virtual file system host (which has more consistent timing characteristics) to the Node.js built-in `fs.promises` in angular/angular-cli@d3bc530c10. NOTE 2: This commit also ensures that files in the `ngsw.json` hash-table are in alphabetic order. Previously, the files were added to the hash-table in blocks corresponding to each asset-group. This change is not necessary (i.e. the order of keys in the hash-table makes no difference in behavior), but it makes it easier to scan for a file (for example, for debugging purposes).
