[IMP] project: replace the basic portal views when project selected

Before this commit, when the portal user is connected and selects a project
in the list when he is in `/my/projects` route, we redirect him in the
task list of this project.

This commit replaces the basic portal view by the project sharing views
if the Project Sharing feature is enabled for this project.
