Invalid length of uuid in status

[craig8]

Describe the bug

This is for python 3.8 (I am unsure if later versions are different)

The uuid displayed by vctl status is incorrect.

>vctl status
9 ieee_2030_5agent-0.1.0   ed1                                     GOOD
2 listeneragent-3.3        listener                                
d listeneragent-3.3        listeneragent-3.3_2                     
f listeneragent-3.3        listeneragent-3.3_1                     
d platform_driveragent-4.0 platform.driver         0 

There should be 2 digits in the uuid position of the status

With the following code I test the method that calculates it

The method _calc_min_uuid_length is used by the platform to determine the length that should be displayed

from collections import namedtuple
import os

Agent = namedtuple('Agent', ('uuid'))

my_agents = [Agent(x) for x in ['9b171ba5-f69f-4895-a69e-b51cf4d78150',
    '2c7c8405-49c8-48eb-86ff-236ebe39da6e',
    'd73a71c8-000f-46aa-8e5f-c4436cf847c3',
    'da2c1f0d-6ce5-4095-843c-3abc861d5199',
    'f5de325c-e723-41e5-9ceb-fae722a40eb6'
]]

def _calc_min_uuid_length(agents):
    agent_ids = [agent.uuid for agent in agents]
    common_len = len(os.path.commonprefix(agent_ids))
    return common_len + 1

print(_calc_min_uuid_length(my_agents))

The output produced is a 1 when the correct value should be 2.

This was merged into develop in #3129.
