App Name does not refresh on re-build

Description

When running app through npm start, the app’s name is not updated in page. It works as expected (app name changed) when running npm run serve though.

Expected Behavior

Modifying the app name in index.ts should change the text in the header on the app

Actual Behavior

Modifying the appName variable in index.ts does not change the text in the header on the app (still says ARCGIS TEMPLATE APP)

Steps to Reproduce

1. npm install -g @arcgis/cli
2. mkdir temp
3. cd temp
4. arcgis create demo .
5. npm start
6. Open src/index.ts in a text editor, and modify the string Template App to anything else (Ex: test)
7. Notice that the webmack build happens, and the page is refreshed, but the title in the page still says ARCGIS TEMPLATE APP

Your Environment

• Version used: @arcgis/cli@4.7.3
• Browser Name and version: Chrome latest
• Operating System and version (desktop or mobile): Windows 10 Enterprise, v1607

My experience seems to confirm this. I installed 4.8.3 on a machine that had not seen any earlier versions of @arcgis/cli and it worked as expected, i.e. service workers not used in development mode.

Seems like this is now working fine for me in v4.13.0. Thanks!
