If A depends upon B which depends upon C and the setscene for B
succeeds but C is going to get rebuilt, we should wait for C to
try and build A but currently we don't.
This is due to the timing of when we run the task_skip() as this
triggers other tasks to become buildable. This patch moves the timing
of that call to a more appropriate place allowing dependencies to
behave as expected.
