Merge pull request #1620 from profanity-im/readd-ci

Re-Enable CI for TW, ubuntu and macos.

For Arch I get:
```
Step 1/24 : FROM archlinux/latest
pull access denied for archlinux/latest, repository does not exist or may require 'docker login': denied: requested access to the resource is denied
```

for both archlinux/latest and archlinux/base.

Let's leave it out :-)
