get_devices_in_container returns devices defined in wrong container

[cheynearista]

We shouldn't be using getInventory for searching for devices in a container. This will return invalid results. Example:

• Define two containers: 'Leaf' and 'Test'
• Create several devices called 'Leaf1', 'Leaf2', etc...
• Move devices into container 'Test' leaving Container 'Leaf' empty
• Perform get_devices_in_container('Leaf')
• This will return any device that has 'Leaf' in the name

One way to fix is to get the Container info from name.
Using the above container info/key, filter out devices that have the parent container key equal.
