base_gengo: [FIX] change http status code for gengo_callback because status 100 make response very slow
[FIX] Cron for gengo was always in mode 'do missed' what we don't want, replace 0 by False
[FIX] Remove unused regexp to find view_id from js which was breaking the count words
[FIX] "prefetching" removing even the records specifically asked for

16d6744 turns out to not be great, because it filters out the todos for
prefetched fields (rather than those just for the field being asked) there are
situations where it ends up not fetching the records it was originally asked
for and breaks a bunch of stuff e.g. unreconcile line in bank statements

Force the ids explicitly asked for back in the fetched set, so that the
prefetch is at most a noop, rco will have to take an actual look at it.
[FIX] remove if in prefect to prefetch all fields (to have same comportment test and prod)
[FIX] res.users: use read method to compute default values to don't create browse record and fetch all fields, browse record crash for install or update module
[IMP] model: when the orm create/update a table check if they are at least one row of the table to load column default values
