Fetch WebView package even if it is uninstalled for the current user.
Fetch WebView package even if it is uninstalled for the current user.

Since the WebView loading mechanism is global - it doesn't differ
between different users, a user for which the current WebView provider
is uninstalled won't be able to fetch any information about the current
provider without passing a certain flag (MATCH_UNINSTALLED_PACKAGES) to
the package manager.
