[repo] kill rebuildinfered feature from Repository.set_schema
This clutters thing and is useless in most cases: when schema just have been
readen from the database or from the file-system, infered relations have just
be calculated.
The only use-case where it should be rebuilt is on migration (ie schema
modification by editing the meta-model using rql), so move this feature there.
