Bug: ambiguous results for degree for self-loops in `ukv.graph`

Describe the bug
The following snippet shows some inconsistency in ukv.graph between results for self-loop in .degree[] and .degree(). First return 2 * w(i, i), but second w(i, i) . NetworkX in both cases return double weight.
Steps to reproduce
import ukv.umem as ukv
import networkx as nx
db = ukv.DataBase()
graph = ukv.Network(db, 'graph', 'nodes', 'edges')
graph.add_edge(1, 1, 0)
print(graph.degree[1]
# 2
print(dict(graph.degree()))
# {1 : 1}
G = nx.Graph()
G.add_edge(1, 1)
print(G.degree[1])
# 2
print(dict(G.degree()))
# {1: 2}Expected behavior
degree counts self-loop's weight with factor 2 in both cases.
