Top-level awaits

[tolauwae]

Problem: Mocha custom reporter still does not support ES Modules.
As long as we use mocha, we cannot have top-level awaits, such as the one in module.ts.

latch/test/module.ts

Line 19 in e549720

const request = await Message.uploadFile(folder + module);

Workarounds like calling an async function do not work either, in that case the tests do not get loaded.

Why we want this fixed: However, awaits when building tests is extremely useful. We often want to compile stuff at this point.

Mocha has been removed, but top-level awaits still don't work in Typescript
