+ The event slice unpacker doesn't correctly extract element from the slice. The indexed arguments are not ignored as they should be (the data offset should not include the indexed arguments). + The `Elem()` call in the slice unpack doesn't work. The Slice related tests fails because of that. + the check in the loop are suboptimal and have been extracted out of the loop. + extracted common code from event and method tupleUnpack
