ASTERIXDB-1415 Fix Feed Freeze with Indexed Dataset

A feed might cause the system to freeze when connected to
a dataset that has secondary indexes. This case happen if
a frame contains all duplicate records pass the primary index
insert operator. The root cause is that the assign runtime in
the pipeline assumes at least a single record. Hence, a corrupted
tuple will reach the commit operator which will create a bad log
record with a PK of size 0. The log record will cause the log
flusher thread to die.
