iwa: Add observer support to IsolatedWebAppInstallerModel

This adds an Observer interface to IsolatedWebAppInstallerModel, and
makes IsolatedWebAppInstallerViewController implement it. This allows
tests to also register as model observers so they can wait for events
in the installer.

This also updates IsolatedWebAppInstallerViewController unit tests
to use the model observer, which makes them more robust and clear.
