Bug: Web tree remove -> paste

[wmoore]

If I right click on a Dataset and "remove", then copy the same dataset from the bottom of the tree and "paste" it back in to the project that it came from, I get the error below.
When I refresh the tree, everything is OK (dataset is back in original project).

Traceback (most recent call last):

    response = callback(request, *callback_args, **callback_kwargs)

(In [81572824ac71224e016beb12c051f89b79517563/ome.git] on branch develop) this fixes the loading error, but still copieng/pasting dataset does not remove orphaned dataset, close #6097
