[FIX] portal,project: allow other company users to correctly access my/tasks page

In multi-company configuration setup, Company A and Company B.
Have a project in Company A that I want to share with a user in
Company B. The user only has access to Company B.
Share using the project link and open using the user

Traceback error will raise.

Adding a default value to retrieve in case the filter option is used
but the user has no permissions on the records.
