Remove printing of edge connections by qgraph

[KarolineHuth]

plot_edgeevidence()

i think it's related to storing qgraph first and then using plot; it's printing both the plot and the weights

[[1]] From To Weight 1 --- 2 1 2 --- 3 1 1 --- 4 1 2 --- 4 1 3 --- 4 1 2 --- 5 1 3 --- 5 1 4 --- 5 1 1 --- 6 1 2 --- 6 1 3 --- 6 1 4 --- 6 1 5 --- 6 1 1 --- 7 1 5 --- 7 1 6 --- 7 1 1 --- 8 1 2 --- 8 1 4 --- 8 1 5 --- 8 1 6 --- 8 1 7 --- 8 1 1 --- 9 1 4 --- 9 1 2 --- 10 1 4 --- 10 1 5 --- 10 1 9 --- 10 1 1 --- 11 1 4 --- 11 1 6 --- 11 1 7 --- 11 1 9 --- 11 1 10 --- 11 1 1 --- 12 1 4 --- 12 1 5 --- 12 1 10 --- 12 1 11 --- 12 1 1 --- 13 1 2 --- 13 1 3 --- 13 1 5 --- 13 1 6 --- 13 1 7 --- 13 1 8 --- 13 1 9 --- 13 1 10 --- 13 1 11 --- 13 1 12 --- 13 1
