Runs onSuccess twice consecutively after a file save.

[eguneys]

When I save a file, it runs the tests and clears the screen and runs the tests again happens in 1 second. So it fires twice consecutively. It's annoying.

Can you provide an example code to reproduce?

[eguneys]

Run yarn watch, make changes in src/pos.ts save.

I don't get see it running twice... only once
note that you can use --noClear flag to see the full output

I think this is happening microsoft/TypeScript#37994
I set --synchronousWatchDirectory and it works ok.
