rugnux: a run that indexes nothing still writes a process file

Browse Source 
With merging on, the _process.h5 is skipped because the merged reflections are
the wanted output and that file is large (113 MB for 200 images here). But if
nothing indexes there are no merged reflections either, so the run finished
successfully having written no file at all - the one case where the user most
needs something to look at.

Write it in that case. The per-image messages have already gone past unwritten,
so this carries the dataset metadata, the mask, the azimuthal profile and the
summary scalars rather than the full per-image tables - and it is small for the
same reason it is needed (124 kB on a zero-index run). A run that does index is
untouched.
