Space images are kept forever

[jvillafanez]

Describe the bug

When you create a space you can edit the space image. You can set different images for the same space for a long time. However, the old images aren't removed from the space, and might take a lot of storage space.

Steps to reproduce

1. Create a space
2. Edit the space image multiple times, use different images each time.

Expected behavior

Only the last uploaded image is kept. The previous images are gone.

Actual behavior

Although the last uploaded image is shown, all the images are kept. You can find the previously uploaded files inside the backend storage.

Setup

Please describe how you started the server and provide a list of relevant environment variables or configuration files.

OCIS_XXX=somevalue
OCIS_YYY=somevalue
PROXY_XXX=somevalue
