No confirmation for failed search

[Danielle Foré]

When you do a search for something with no results, you get a blank page. It would be good to have some sort of confirmation that the search has indeed been completed, yet yielding no results. I've attached a screenshot of Google's no search results page as a reference.

I implemented a sort of error display which is now used in case of no search results or an account where fetching folders failed.

@ Christian:
If you search something and there are no hits,the message still isn't shown. I gave a look at the commit you've made and I may have figured out what the problem could be. At about line 747 of postler-messages.vala you've put:

if (location.has_prefix ("search:") && n_messages == 0) {
                display_error (_("No messages found"),
                    _("Check the spelling or try a different filter."));
                 return false;
            }

The AND should be replace by an OR (which in my case worked).
Hope I didn't say something stupid..=)

Your suggestion is not quite right, since it would show on empty folders as well. But you brought me to a better idea: to actually check if we had any filters.
