auto-connect fails to parallelize independent processes

[Olivier Dion]

Hi,

Given the following example:
--8<---------------cut here---------------start------------->8---
process proc (with output)
  packages "coreutils"
  outputs : file output
  # {
    for i in $(seq 10); do
      date >> {{outputs}}
      sleep 1
    done
  }

workflow parallel
  processes
    auto-connect
      proc "A.out"
      proc "B.out"
--8<---------------cut here---------------end--------------->8---

We can see that both processes are completely independent, and yet they
are batched linearly.

If we re-write the workflow with `graph' instead:
--8<---------------cut here---------------start------------->8---

define A : proc "A.out"
define B : proc "B.out"

workflow parallel
  processes
    graph
      A ->
      B ->
--8<---------------cut here---------------end--------------->8---

we do get parallel execution of the processes.
