Fix "-Sd conflict_pkg" bug

Browse Source 
If the -d switch was invoked with -S (or -U), the removes list was simply
lost, because trans->remove was computed in an
"if(!(trans->flags & PM_TRANS_FLAG_NODEPS))" block.

I've added a new pactest file, sync045.py (derived from sync043.py) to test
this.

Additionally, I did some other minor cleanups in sync_prepare:
 * preferred list is not needed anymore
 * I removed a needless alpm_list_remove_dupes line (the target list should
   not contain dupes at all)
 * I moved alpm_list_free(remove); to cleanup part to eliminate a possible
   memleak
