Unexpected constraint query string causes 500

[jrochkind]

I think it's that the params look like:

"f" => {"subject_facet" => {"0" => "Scientific apparatus and instruments"}},

A hash instead of an array. Not sure if our app produces this input somehow, or if it's just a bot trying it's own generated URLs.

But either way, unexpected input should probably not result in an uncaught exception, but should give a more well mannered error of some kind. This could be something that should be PR'd to Blacklight itself.

Needs more investigation.

Very similar to #589, actually kind of a dup of that, exccept it's not place-specific after all.
