Fix initializing the app twice
Fix initializing the app twice

When Talk is embedded in the public share authentication page the app is
explicitly initialized in "publicshareauth.js" (as some special setup
for the settings will be needed in that case); "init.js" should be used
only for the regular Talk app.
