Release v0.4.1 breaks legendas

[jteijema]

Using the following code with the API from version 0.4 gives no errors when creating a plot with a legenda:

with Plot.from_paths(files[:1]) as plot:
  inc_plot = plot.new("inclusion", result_format="number")
  inc_plot.set_grid()
  inc_plot.set_xlim(0, 4000)
  inc_plot.set_legend()
  inc_plot.add_random(add_text=False)

  all_files = all(plot.is_file.values())
  for key in list(plot.analyses):
      if all_files or not plot.is_file[key]:
          inc_plot.add_wss(
              key, 95, add_value=False, add_text=False)

  inc_plot.fig.set_size_inches(10, 5, forward=True)

  inc_plot.show()
  inc_plot.save("simulation_results.png")

Whereas running the same code with version 0.4.1:

The error message isn't very informative.

..\Python\Python39\lib\site-packages\asreviewcontrib\visualization\plot_base.py:32: UserWarning: Legend does not support [<matplotlib.lines.Line2D object at 0x000001F563215400>] instances.
A proxy artist may be used instead.

  self.ax.legend(self.legend_plt, self.legend_name, loc=loc)

No idea what causes this: https://github.com/asreview/asreview-visualization/compare/v0.4...v0.4.1.

Judging the difference it can only have been #20.
