comparison/mutations tab fails to load if mutations are not selected on genomic alterations tab

[tmazor]

If I de-select Mutations on the Genomic Alterations tab, and then click over to the Mutations tab, the page fails to load and I get this error:
{"type":"ErrorBoundary","log":"TypeError: Cannot read properties of undefined (reading 'hugoGeneSymbol')","url":"https://www.cbioportal.org/comparison/mutations?comparisonId=6138b02de6ebe01a6ee2de0b&unselectedGroups=%5B%22LGG_IDHwt%22%2C%22NA%22%5D&selectedEnrichmentEventTypes=%5B%22HOMDEL%22%2C%22AMP%22%2C%22structural_variant%22%5D"}

If I re-select Mutations on Genomic Alterations, then the Mutations tab loads cleanly.

The Mutations tab should load even if mutations have been deselected on Genomic Alterations.

@inodb @alisman can we prioritize getting this fixed?
