Please describe the expected behaviour

When editing resource metadata, we should store the filename in the database, at resource table URL column.

Please describe the actual behaviour

When editing resource metadata, full URL is saved in the database

What steps can be taken to reproduce the issue?

1.Go to edit resource page
2.Save the changes

I've tested of this occurs on edit dataset and the issue is not reproducible.It occurs only on edit resource.

This occurs because we are generating the full url on reading the resource and it is stored as it in the DB on save
