Modules loading and unloading other modules has never really worked
well; there have always been lots of weird gotchas along the way.
In this case, the "module unload" is causing the TWO_TEST environment
variable to be unset. Modules is not aware that the two modules use
the same environment variables since you don't use "conflict" or "switch".
I'd use "conflict" statements instead if I were you.
You really want to be doing a "module switch" for the two modules,
anyway - the proper command is "module switch test1 test2". But don't
do that in the test2 modulefile, do it on the command line after
checking if the module is loaded.
