In edit mode, when new nodes are created in senquence they are created with the default name "State" causing naming conflicts. In accordance with Serverless Workflow specification we cannot have states sharing the same name.

In order to not break the worflow, at the moment of the creation of the new state, the availability of the name must be checked.

Expected behavior:

• If there is no other State with the default name "State", the State must be created with de default name.
• If there is naming conflict, a numeric suffix must be added to the default name e.g. "State_1"
• If there is naming conflict after the addition of the suffix, the numeric suffix must be incremented e.g. "State_2"
