Join tasks work incorrect after rerun

[Oleg Ovcharuk]

Let's consider this example:

wf1:
type: direct
tasks:
  t0:
    action: std.noop
    on-success:
      - t3
  t1:
    action: std.http url=some_unstable_url
    on-success:
      - t3
  t2:
    action: std.http url=some_unstable_url
    on-success:
      - t3
  t3:
    action: std.noop
    join: all

HTTP actions failed for the first execution, we fixed this url and decided to rerun t1 and t2.

Rerun of t1:
Expected result: t2 and t3 are still in ERROR state
Actual result: t3 is in SUCCESS state, ignoring it's logical state

Rerun of t2 after previous rerun:
Expected result: all tasks are in SUCCESS state, t3 has 1 action execution
Actual result: t3 has 2 action executions
