Current behavior

cordova builds use base href "./" and web builds use base href "/". I believe this was to work around a webview bug that's now been closed. I tested with an iPhone X and a Xiaomi android and it doesn't seem necessary anymore.

Expected behavior

base href="/" in all cases.

Minimal reproduction of the problem with instructions

Environment

- generator version: 6.x
- node version: 10.x  <!-- run `node --version` -->
- npm version: 6.x  <!-- run `npm --version` -->
- OS:  <!-- Mac, Linux, Windows -->

Does it work on iOS with ionic-webview-plugin and HTML5 routing enabled? (hashbang routing is forced on mobile if I remember well, because it led to routing issues)

If it works now everywhere, yes we should definitely update that! :)

Hmm I didn't try hashbang routing, but on PathLocationStrategy it seems to work well. I guess it might be safer to try this after the CI app builds are all set up so I don't break something.
