Hotfix/initialization checks

[james-toussaint]

• Added checks before upgrading locally to initialized status
• Removed 2-blocks waiting time before supplying new replicate
• Minor logs update

Aren't those 2 lines redundant? It looks like we are sure that the last status in the dateStatusList is equal to the current status.
(That's enforced in Task class so I'm not sure we should test it here.)

I see your point yes, I might say current version helps reading. Let's take this example:

        assertThat(task.getDateStatusList().get(task.getDateStatusList().size() - 3).getStatus()).isEqualTo(RECEIVED);
        assertThat(task.getDateStatusList().get(task.getDateStatusList().size() - 2).getStatus()).isEqualTo(INITIALIZING);
        assertThat(task.getDateStatusList().get(task.getDateStatusList().size() - 1).getStatus()).isEqualTo(INITIALIZED);
        assertThat(task.getCurrentStatus()).isEqualTo(INITIALIZED);

1. Last assertion helps reading quickly what's the targeted status at the end.
2. Three first assertions are kind of optional tests checking status orders, easy to read them out in one block.

Anyway, if we can discuss on that, I don't feel confident with refactoring these tests in this hotfix PR.

Alright, I'm OK with that. Thanks!

Good, thanks!

Ok for me, thanks!
