Share still exists after source file gets deleted

[Emi94]

Steps to reproduce

1. Share a file with a user
2. Delete the shared file

Expected behaviour

Share should be deleted from DB

Actual behaviour

Share still exists in DB table oc_share

Server configuration

Operating system:Ubuntu 16.04
Web server:Apache2
Database:PostgreSQL
PHP version:php 7.0
Nextcloud version: 12.0.3
Updated from an older Nextcloud/ownCloud or fresh install:updated from older nextcloud
Where did you install Nextcloud from:https://nextcloud.com/install/
Are you using an external user-backend, if yes which one: LDAP

This lead to one user having a broken share in "Shared with others" folder:

I managed to get rid of it by manually deleting the share from DB table oc_share.

I would recommend for nextcloud to check when deleting a file, if it is shared. If yes then delete the share from DB too.
