[BUG] `enumerate_paths` does not give all paths

the function enumerate_paths, when passed a DijkstraState, does not enumerate all paths as advertised.

below, I create a minimal example.

	# construct graph
	my_g = SimpleGraph(5)
	add_edge!(my_g, 1, 2)
	add_edge!(my_g, 3, 2)
	add_edge!(my_g, 2, 4)
	add_edge!(my_g, 3, 4)
	add_edge!(my_g, 5, 4)
	add_edge!(my_g, 5, 3)

	# find all shortest paths from node 5 to other nodes
	my_dsp = dijkstra_shortest_paths(my_g, 5, allpaths=true)

	# enumerate paths from node 5 to 1
	print(enumerate_paths(my_dsp, 1)) # only gives one path!

	graphplot(my_g, nlabels=["$i" for i = 1:5])

Expected behavior
I expect enumerate_paths(my_dsp, 1) to give both:

[5, 3, 2, 1]

[5, 4, 2, 1]

but it only gives one of the paths.

[86223c79] Graphs v1.13.2

Start with enumerate_paths and the DijkstraState produced by dijkstra_shortest_paths(..., allpaths=true), then reproduce the minimal five-node graph from the issue. Trace why enumerate_paths(my_dsp, 1) returns only one route; done means it returns both expected shortest paths, with the existing behavior verified against this example.
