When a capture file is reloaded, the information stored in
VoipCallsInfoModel is invalidated. Add another cache layer to fix this:
VoipCallsInfoModel wraps around raw data (invalid on close)
CacheProxyModel NEW: use prev. data or cache on close
VoipCallsInfoSortedModel provided sorting, etc.
VoipCallsDialog actual user of model (callTreeView)
This also fixes a UAF after a file was closed, and when a call is
selected (that got worse with the last model/view patch and is "fixed"
in this patch with the caching layer. Note that the Flow sequence and
Play Streams dialog are not that useful when the file is closed).
