Title: Ignore conditions without a predicate (instead of raising an error)

We're seeing a few `No valid predicate for ...` errors from our support staff trying to manually edit the query strings in our searches.

To solve the above we're cleaning the params before passing them through to Ransack, but it would be nicer if Ransack just ignored these badly-specified conditions, in the same way it ignores terms which don't relate to an attribute.
