[IMP] crm: improve team pipeline dashboard leads/opps counts performance

The team pipeline dashboard fields
`unassigned_leads_count`, `opportunities_count`, `opportunities_amount`

do a big search on leads, filtered
by type (lead/opp), team, and unassigned user_id (salesman)

Adding an index on user_id, team_id, type significantly
improves the filtering, and therefore the dashboard rendering,
especially when displaying a few teams only
e.g; the teams you are part or responsible of.

The index on `user_id` is removed,
as it become a duplicate as `user_id` is the first column
of this new index.
