Enhanced community/colletion logo edit

[Sondissimo]

Description When editing an existing Community/Collection the Dspace standard behaviour is redirecting the user back to the Community/Collection page, after it uploads/remove the selected logo. With this PR it's possible to handle the logo remaining in the same edit page. When creating a new Community/Collection the current behaviour for the logo upload is kept.

List of changes in this PR:

• Logo editing is now handled inside the edit itself
• Updated tests to reflect new behaviour

Instructions for reviewers: Please try removing/uploading the logo in community/collection edit Please try creating a new community/collection with and without logo

We have tested this PR. Checked out the PR branch, after uploading a logo, it appears and can be deleted, without being redirected from the edit page. Works as described.

@Sondissimo : If you can find time to fix the bug that I reported in my prior review, we still have time to include this in 8.0. Otherwise, we may need to reschedule it for 9.0

The bug reported was present on Dspace8 already, we provided a fix for it in the last commits 😊
