Explicitly check for an installed WebAPK before starting installation

This CL moves the checking for whether a WebAPK is already installed from
GooglePlayWebApkInstallDelegate to WebApkInstaller. This enables checking
whether the WebAPK is already installed only for installs and not updates.

Previously, the check was done for both installs and updates and prevented
updates from occurring.
