Deno cannot find tests in sibling-directory anymore

[bodograumann]

After updating deno from 1.39.2 to 1.40.2, it cannot find our tests anymore.
It seems to be related to them being in a sibling directory.
I have created a reproduction here: https://github.com/bodograumann/deno-cannot-find-tests

$ git clone https://github.com/bodograumann/deno-cannot-find-tests
$ cd deno-cannot-find-tests
$ deno test server
Check file:///home/bodo/Reproductions/deno-cannot-find-tests/server/example.test.ts
running 1 test from ./server/example.test.ts
url test ... ok (0ms)

ok | 1 passed | 0 failed (2ms)

$ cd dist
$ deno test ../server
error: No test modules found

Version: Deno 1.40.2
