fix: add global test registry (denoland/deno_std#568)

Browse source 
After adding deno test command a new problem appeared.

If you try running deno test inside this repo test runner will find 
80 test files but won't run any tests! This is caused by fact that 
deno test uses tagged version of standard library which causes 
test function available inside to repo to be different function that 
test available in standard lib used by deno test.
