Validate that one of streams choosen in logs on api side

Fixes #6506

There is the bug, that very hard to fix: When we return job.Errorf in
"logs" job it writes to job.Stderr, to which connected ResponseWriter and on
this write w.WriteHeader(http.StatusOK) is called. So, we get 200 on error
from "logs" job.

server: buildfile: ensure that ONBUILD triggers aren't committed

This patch fixes the bug where ONBUILD triggers are committed each build
step created during the ONBUILD trigger execution, since the triggers are
only wiped *after* all ONBUILD trigger steps have been committed. This was
fixed by simply copying the ONBUILD triggers and wiping the config
*before* committing anything.
