LegacyApplication explicitly uses "reindeer" as default theme.
Extended AbstractTestUI to AbstractReindeerTestUI, that all old tests now inherit.
All new tests should be based on AbstractTestUI.
Also added AbstractReindeerTestUIWithLog for those that needed it.
Removed all found @Theme("valo") and used proper parent test class.

Properly cleanup stream variables if DragAndDropWrapper is detached (#14882)
If DragAndDropWrapper is removed from the UI for whatever reason before cleanup
happens, the UI can no longer be found through it. If we do not do cleanup, we
leave a reference hanging forever in ConnectorTracker.

Make sure that no fileIds are replayed to the client (#12330)
Due to how ProxyReceivers are constructed and serialized, we don't want
to resend the ProxyReceivers for files that already are in the queue.
Either we needed to change the way ProxyReceivers behave, or just make
sure that they aren't resent. I chose the double-check method.
