[BUG] Uploading new custom modules versions don't remove deleted module hooks/actions

[davidvitora]

Describe the bug
When you upload a new custom module version, if you deleted a hook/action from the module, it is not deleted from the Botpress server when you upload the new version.

To Reproduce
Steps to reproduce the behavior:

1. Create a custom module with a hook/action
2. Upload to the Botpress server, check if those actions/hooks were created.
3. Create a new custom module without these hooks and upload it to the Botpress server.
4. Check that the hook/actions were not deleted.

Expected behavior
Botpress to remove deleted files.
