Copy & Paste is not Correct Using Stand Alone Slaves

case 1:

• Add a master to the root line
• Add a stand alone slave to the root line
• Copy the slave and paste it at the master
• Open master GUI

-> The slave is missing in station table, process data and address table

case 2:

• Add a stand alone slave to the master
• Copy the slave
• Paste the slave at root line

-> The slave is not added and a confusing message is shown in output view: "Master not found. Please install the master device: <not found>"
