Fix randomly failing spec on Sqlite

[repomaa]

The spec is currently skipped for Sqlite. See #191. Currently it seems the bug is only reproducable on linux (and therefor travis). Suspect it being a timing issue.

Tried to reproduce using Docker, but no luck :(

I'll have to fire up a linux VM.

Still cannot reproduce in an Ubuntu 18.04 vm ☹️

Thinking about maybe moving the specs to use docker instead?

Hi! I also tried to reproduce it (regular Linux installation, no VM), but with no luck. Are you sure the issue still exists?

I just re-ran the sqlite specs on PR #204 and it passed ?!?

Maybe its fixed somehow?
