fix: At oncomatrix, allow gene expression term to pull data on all cases

[xzhou82]

Description

please test on adhoc map with genexp already added note that the term shows exp values for 219 cases

very slow! 100 seconds. it queries gene exp data twice, each 50 seconds. first time is fillTw() getting binning. 2nd time is to pull data

in next pr may apply a hardcoded dummy default bin for gdc gene exp terms. for local ds this is not an issue and won't do this

I noticed (also on master) using this example link, replacing a gene exp term is not always smooth and shows some errors sometimes after replacing and trying to use some other features of the matrix.
