Activity parent resource refs

[kulmann]

Describe the bug

For most file location related activity items I'd expect the target or parent folder to be referred to in the activity message. Instead, only the space itself is referenced.

Steps to reproduce

1. Create a Space Space
2. Create a folder folder
3. Create a subfolder folder/subfolder
4. Create a file test.md inside folder
5. Move test.md to folder/subfolder

Expected behavior

• Activity message for (3) is admin added subfolder to folder or admin added subfolder to folder in Space (up to @tbsbdr to decide)
• Activity message for (4) is admin added test.md to folder or admin added test.md to folder in Space (up to @tbsbdr to decide)
• Activity message for (5) is admin moved test.md to subfolder or admin moved test.md to subfolder in Space (up to @tbsbdr to decide)

Actual behavior

Activity messages actually are:

• admin added subfolder to Space
• admin added test.md to Space
• admin moved test.md to Space

I've lowered the priority to p3, we can work on this in the next sprint. No immediate fixing needed.
