Gene Grid - aliases in 1 build but not the other

Gene grid is genome build independent.

Gene symbols like HOX3H that aren't associated with any gene but are an alias (via HGNC) will show up as aliases (ie the yellow line with a link saying it's an alias and add the real gene symbol to the grid)

TMEM5 is a valid symbol for the gene in 37 but not in 38 - so it's not strictly an alias to that symbol in all cases, ie you may want to see the coverage in some kits / use it in a gene list

TMEM5 and RXYLT1 both match to GeneID:10329 - though what should happen is:

* GRCh38 symbol/gene assignment should indicate it's via an alias
* Coverage should also handle the alias (which it doesn't).
