blank search + 'only show eBooks' -> null pointer exn

[Mike McCabe]

http://upstream.openlibrary.org/search?has_fulltext=true

... leads to a (working) page whose contents are a Java null pointer exception stack trace.

[George (george-archive)]

So, if someone submits a search with an empty search box, and the ebooks box checked, it should mimic the (current) behaviour of submitting a search with an empty search box and the ebooks box not checked. That is, go to http://upstream.openlibrary.org/search

(Incidentally - that layout on search is broken for me, in this case.)

I cleaned up the "No Search Entered" layout but I don't know where in the template to highjack the "ebooks only/no search" input that's yielding SOLR's Java errors.
