[FIX] hr_timesheet: project stat button on analytic account

Before this commit, when more than 1 projects are linked to
a same analytic account, clicking on the stat button from the
form view of analytic account, nothing happens.
This commit fixes this case by displaying the kanban view
of all the project linked to this analytic account.
