PartitionManager - flickering when switching devices

SUMMARY

After switching devices in a side bar, most of the time user may see a fast (~1 frame) flickering of the device partitions charts.

STEPS TO REPRODUCE
1. Have at least two devices attached.
2. Open partition manager and authorize
3. Switch devices back and forth

OBSERVED RESULT
Flickering instead of crossfade or any other smooth transition.

EXPECTED RESULT
Buffer previous chart until the data for a new one is ready. If it takes too long for the data to load, e.g. more than half a second, hide an old chart and show a loading indicator instead.
