After a Slave Instance is created, one Sale Packing List with resource == "vifib_instance_setup" and simulation_state == "confirmed" is created. With this cenario, is needed make mofications in the Software Installed installed. So, this changes is to request modifications in Software Instances after one Slave Instance is requested.

juntar os testes because the sequence of steps are the same. I will only join the steps to check the states of Sale Packing Lists because is only the part that is different.

use uid instead of reference because two computer partitions can use the same reference but each partition is installed in different computer

prefix step is not required and add stepTic to commit the transactions after SoftwareInstanceStarted

Possible this test detected another failing use case during destruction.
That's why it is still marked with NotImplementedError

add interaction to change the state of Sale Packing List with state "stopped" to "delivered"  when startComputerPartition() is called

fix steps because this test must validate if the Slave Instance is stopped correctly according to one production scenario

Force the update of Computer Partition is any Slave Instance is allocated
or stopped. This make the system automatically update configuration if
the new slave instances be created.

add steps to install another software release in the current computer partition to force allocate the Slave Instance in different computer partition

When some Slave Instance allocated on some computer partition, it
trigger the "start" broadcast and sometimes some Sale Packing Lists are
already started, long ago.

Refactor steps to validate if the exception NotFoundError is raised correctly when a software release is not installed in the selected computer partition

Add step to select a random computer partition. This method is used to select one computer partition that does not exists one software release and one software instance installed in this partition. For now, the first one is enough

Revert "add step to be possible select a random computer partition. For now, select the first one is enough. This step will be used to raise the exception NotFoundError"
