Valuator: error when trying to answer a suggestion assigned to me and other 🪲

[martanducas]

Describe the bug
As a valuator, when a suggestion is assigned to me, if there are multiple participatory documents in the participatory space, I have found multiple issues:

• In can see all the participatory documents, and all the suggestion assigned to me in all of them. I don't know to which participatory document each suggestion belongs.
• If a participatory document has not uploaded the PDF document, I get a server error (Participatory Document 1 in the video).
• If I try to answer a suggestion that has been assigned to me, I get an error.
• If I click to "Assemblies", I don't know how to go back to my assigned suggestions.

To Reproduce

1. Create and publish multiple participatory documents in a participatory space
2. Create a suggestion and assign a valuator
3. Login as a valuator and try to answer the suggestion

Expected behavior
I expect:

• Viewing only the participatory documents where I have suggestions assigned. Each participatory document should only display its suggestions.
• As a valuator, I have to be able to answer a suggestion.
• If I go to Assemblies/Processes, I should view the Assembly/Process where the participatory document belongs.
