Impacted versions: 11c, 11e

Steps to reproduce: Install module, uninstall it, then go to action choise delete module (tested with some module: Automated Translations through Gengo API, Vietnam - Accounting...)

Current behavior:
Popup error:
```
The operation cannot be completed, probably due to the following:
- deletion: you may be trying to delete a record while other records still reference it
- creation/update: a mandatory field is not correctly set

[object with reference: Module Uninstallation - base.module.uninstall]
```

logs:
```
ERROR: null value in column "module_id" violates not-null constraint
DETAIL:  Failing row contains (1, t, null, 1, 2017-11-06 09:26:04.803957, 1, 2017-11-06 09:26:04.803957).
CONTEXT:  SQL statement "UPDATE ONLY "public"."base_module_uninstall" SET "module_id" = NULL WHERE $1 OPERATOR(pg_catalog.=) "module_id""
```

If module is not installed before, no error occurs

Expected behavior: the module should delete normally
