t-SNE plot is off for rdata loaded from previous NMF run

In saved NMF run, the .rda will include tsne_2d and tsne_3d which is run using original sample order. However, we implement the option to automatically reorder the heatmap_data once we hit run NMF, so the ordering of the samples will be different between these two data We can create another data called filtered_data which will be used by heatmap, PCA, and t-SNE plot. Then the ordering can be done for each of them separately.

Since PCA and t-SNE plots still need to use the Upload Gene List and other filtering functions, we isolate heatmap_data alone and let all the other plot functions use another variable plot_data
