Title: Decouple saving figure from plot_pca in interactive_pca

Thanks to @jasongrout, we modified the `interactive_pca` code so the saving widget is created after the pca widget, so the saving is performed after calculation, and a single change in the textbox doesn't prompt re-calculation or creation of a new file.
