Only perform autolaunch if list has completely rebuilt

Previously we would check for autolaunch the first time
onPostListReady is called, but that is too early in the case
when we start the async task for sorting the targets. In
that case onPostListReady is called twice - once before
task is launched, and once after task is finished.

We fix this by passing the rebuildListCompleted parameter to
the onPostListReady callback and use it to check for autolaunch.
