cyto_plot_gating_scheme fails when OR gates are contained in the gating template

[danychauvin]

Describe the bug
When trying to use cyto_plot_gating_scheme on my data, using a gating template containing a OR gate, nothing is plotted, and I get the following message:

Only NOT boolean gates are supported.
Error in FUN(X[[i]], ...) : NA does not exist in this GatingHierarchy!

To Reproduce
Steps to reproduce the behavior:
Apply a gating template to your dataset, with an OR gate. Try to run cyto_plot_gating_scheme.

Expected behavior
It should plot all gates that are not OR gates.

Desktop (please complete the following information):
