Current behavior

When run the build script with the inline argument of --base-href /current/ and in the ngsw.json file use the absolute path for the files, it produces the path /current/index.html in the built ngsw.json. Using of the relative path in the ngsw.json does not help.

Expected behavior

Either using the relative path in the ngsw.json or generating the output due to the --base-href value.
