Bad thumbnail handling

[etj]

Expected Behavior

• A single thumbnail file should be generated when a Resource is created.
• The thumbnail file should be removed when the Resource is deleted.

Actual Behavior

When a Document is created, two files are created, e.g.:

-rw-r--r-- 1 root root 17135 Jul 16 07:11 document-886bda39-8560-40b2-b9a0-66104147b254-thumb-e5a132a7-57b7-43d2-bcf0-52d4af6fe3e0.jpg
-rw-r--r-- 1 root root 17135 Jul 16 07:11 document-886bda39-8560-40b2-b9a0-66104147b254-thumb-e5a132a7-57b7-43d2-bcf0-52d4af6fe3e0_3ClS2qX.jpg

When the Document is removed, the files are kept.

Other Resource types should be checked.

Steps to Reproduce the Problem

1. Create a Document
2. Check the thumbnail dir for files containing the resource UUID
3. Remove the Document
4. Check if the files still exist (they do)

The thumb is saved twice. The first time here: https://github.com/GeoNode/geonode/blob/4b6d872682ef0efd1ae61bf515b1f7d2250ba448/geonode/base/models.py#L1555

Then again after cropping:

This is valid for all the resources not only documents. Still to be analyzed why is not deleted
