TDI-30183 fix bug: The tLogRow name is wrong when I do copy&past&delete
for job then do copy&past agains
https://jira.talendforge.org/browse/TDI-30183

Fix bug:
 Studio will crashed:
  1. Create a MR job, and add a node
  2. delete this node
 the result is studio will crash

Reason:
In MR job, the container of nodes will contains it self too.
so "jobletContainer.getNodeContainers()" will return a list which
contains itself, so this case make the function falling into dead loop.

Resolve:
I add a readedContainers set to make sure this function will never read
a container which he has read in case of falling into dead loop again.
Merge branch 'maintenance/5.6'
