"oJob options" not handling args expressions

[nmaguiar]

Description
When using a "oJob options" where the args of a specific target job, to be called given an option, is an expression it doesn't seem to get processed (initially reported by @abrizida)

To Reproduce
Steps to reproduce the behavior:

1. Build an oJob similar to:

todo:
- (optionOn): opt
  ((todos )):
    start:
    - name: test
      args: |
        [{ a: 1 }, { a: 2 }, { a: 3 }]

jobs:
- name: test
  exec: |
    print("A = " + args.a)

2. Execute it with ojob test.yaml opt=start
3. Observe that the job "test" is not correctly invoked.

Expected behavior
It would be expected that the job "test" executed 3 times with the different values of a from the array set as an expression.
