  LDA Sieve plugin: Fixed assert failure caused by earlier sieve_discard changes.

The simplest case in which all normal scripts maintain the (implicit) keep action triggered an assert failure.
Fixed by restructuring the script execution loop to make it easy to understand.
Now handles each case explicitly.
