Remove webstore code for signin that is no longer used.

Remove webstore code for signin that is no longer used.

Now that the webstore does not require sign in for apps, the code to
support the signin as part of install flow is no longer required.

Some code is still needed to support paid apps.

surkov - before sending this out, is it OK to remove the signin function? I
tested installing paid apps on chrome built with this change and it was OK.
