When clicking on "CRM -> Reporting-> Leads (Leads Analysis)" list and form
views are not correctly set, leading to opportunity views. In this commit we
* have changed the list view from ``crm_case_tree_view_oppor`` to
``crm_case_tree_view_leads`` to ensure we use the right view;
* we are now able to open form view from the list view like all other views;
When clicking on "Teams -> Reporting (on a team vignette) -> Leads" list
view used is the opportunity one. We fix it by correctly setting action
views for ``action_report_crm_lead_salesteam`` reporting action.
