Jira issue: WP-717: Node crash when installing a widget

This PR addresses this Jira issue. There are two underlying issues:

- a bug in the Java bridge which caused a crash and/or memory corruption under certain circumstances with multiple isolates. This has been fixed in the anode tree and the updated binary is included here;

- a problem sharing resources across the PZP and the Widgetmanager isolates, which are separate isolates on Android. This was caused by the AppLauncher API loading the widgetmanager. This has been temporarily disabled in this PR (for Android only) until some wider rework has been done, either to run the widgetmanager entirely in the PZP isolate, or to enable the AppLauncher to interact remotely with the widgetmanager.
