[IMP] base: rationalize indexes on ir.model.data

Browse Source 
Indexes on individual columns (module, name, model, res_id) have been dropped,
and the index on (model, name) was duplicated in a unicity constraint.  We have
kept two useful indexes, namely:
 - a unique index on (module, name)
 - a simple index on (model, res_id)
