### Reduced chance of losing metadata on Edit Dataset Metadata page

The remedy for the problem consists of two parts:
* Do not show the _host dataverse_ field when there is nothing to choose. This mimics the behaviour for templates.
* When you accidentally start typing in the _host dataverse_ field, undo the change with backspace, fill in the other metadata fields and save the draft, the page used to get blocked due to an exception. Reloading the page would erase all your input. The exception is remedied by looking for the root dataverse.

The method isHasDataversesToChoose() calls dataverseService.findAll().size() every time it's invoked, which could be expensive if there are many dataverses. Consider caching this value or using a more efficient query to count dataverses.

Suggested change
this.hasDataversesToChoose = dataverseService.findAll().size() > 1;
this.hasDataversesToChoose = dataverseService.countDataverses() > 1;

DataverseServiceBean.getDataverseCount() exists and could be used here. - countDataverses() doesn't exist.

@qqmyers mised these comment so far. Got another suggestion form copilot, perhaps more elaborate to implement but might be more effiecient

Query q = em.createQuery("SELECT 1 FROM Dataverse d");
q.setMaxResults(1);
boolean exists = !q.getResultList().isEmpty();

Hmm - with maxResults set to one, you'd never know if there was more than one (thanks Copilot!), but I guess it could be limited to 2 instead.
That said, I think they key thing is to avoid getting a list of objects - that's a big expense.

From a quick test, getting two rows is cheaper than getting the count, but both are orders of magnitude less than getting the objects.

I guess since limiting to 2 rows will scale better than getting the count, I guess this approach makes more sense if you're willing to implement it.

Just logged the duration on a VM with almost 100K dataverses

findall: PT15.632S
getDataverseCount: PT-0.026S

Looks good enough with less effort.

FWIW - the root dataverse does not always have id=0

FWIW: There is a findRoot call that could be used instead.

@jo-pol can you please switch this to dataverseService.findRootDataverse() instead? Thanks.

return dataverseService.find(pk);
//return dataverseService.findByAlias(submittedValue);
