inconsistent state unhandled by services setup

Package version (if known): invenio-cli, version 0.23.0 (python 3.7.1, using postgresql as db)

## Describe the bug

An inconsistent state makes `services setup` (and `service setup --force`) fail at an intermediate point during the db setup (even if the table creation successes). When this happens, the workaround is to delete the psql docker container and re run `services setup` to recreate it.

## Steps to Reproduce
1. Run
```bash
invenio-cli init rdm
cd my-site/
invenio-cli install
invenio-cli services setup
```

```
