fix jest transpiling all node modules, make tests fast again (#522)

the previous regexp is bugged, it requires '//' in the filename !!
As a result, all the files in node_modules don't pass the regex
so nothing is ignored => everything is transformed

jest caches this in /tmp/jest_* so rerunning tests is fast, but
the first time jest takes minutes to transform everything

also the previous regex was incomplete (missing other files that need transforming)
but this was not visible because it transformed everything anayway

use the same regex as gridstudy gridexplore for consistency...
