Expose Chrome version to todos webview (fix #1211) (#1478)

* Expose Chrome version to todos webview (fix #1211)

The TickTick todo service fails to load if the Chrome version number
does not appear in the User-Agent string. However, login to Google Tasks
is prevented by the same.

We adopt the "chromeless" User-Agent logic from the service webview,
which selectively exposes the Chrome version everywhere except the
Google login screen. The common logic was moved into the
userAgent-helpers module.

* Refactor user agent switching

* "Chromeless" user agent switching is extracted into a separate model
* Both the service and the todos webview uses the same model
