Failing check in predict_position()

[moi-taiga]

The check for whether subset_switching_genes() has been run, doesn't work if the sample is smaller.
Need a different method for checking if subset_switching_genes() has been run.

Error in predict_position(p16_sce, switching_genes) :
The number of genes in the reduced binary counts matrix is
greater than the number of switching genes.

Make sure you have run PathPinpointR::subset_switching_genes()
