Fix T36263: Pasted strip doesnt have F-Curve keyframes from the original

Original code for copying strips tried to change strip name 2 times before
copying and once again after pasting.

Store structs in clipboard in unchanged state, so we can reference data after
pasting easily.

Better method would probably be storing animation data in clipboard as well,
so we can copy animated strips even between scenes.
