Use generate_sequence instead of from_elements for zero vectors

Using from_elements with a list of zero elements can cause timeouts
for large parameter values because those values have to be sent to
Flink before the job is run. Instead, generate a sequence of the
desired length and assign a value to each of the elements; this should
solve the timeout issue.
