Describe the bug

Debugging and hot reload is broken when app base path is changed in index.html and launchsettings.json.

Expected Behavior

Debugging and hot reload with a different base path should work

Steps To Reproduce

Repo reproducing problem here: https://github.com/daytonjallen/HotReloadPathIssueRepro

1. Start new blazor wasm project
2. Update base path in index.html
3. Update paths in launchsettings.json (problem exists when using both the IIS & http run configs)
4. Try to debug project

App will fail to load due to exceptions from not finding blazor-hotreload.js etc:

Exceptions (if any)

blazor.webassembly.js:1
