Error when doing a query on resources

[pombredanne]

I run a "scan_single_package" scan with this (large) input https://github.com/moby/buildkit/archive/refs/tags/v0.13.2.tar.gz

Then I go to the Resources page and eventually I craft this (possibly incorrect) query in the search box:

-detected_license_expression=:apache-2.0 -detected_license_expression=:"apache-2.0 AND bsd-new" " 		-detected_license_expression=:"apache-2.0 OR gpl-2.0-plus"

I get a 500 error.

https://<scancode.io>/project/httpsgithubcommobybuildkitarchiverefstagsv0132targz-e51adcdc/resources/?search=-detected_license_expression%3D%3Aapache-2.0+-detected_license_expression%3D%3A"apache-2.0+AND+bsd-new"+"+%09%09-detected_license_expression%3D%3A"apache-2.0+OR+gpl-2.0-plus"&detected_license_expression=ANY&sort=detected_license_expression#syntax

The extra quote in the middle of the line is the culprit because this does not fail:

-detected_license_expression=:apache-2.0 -detected_license_expression=:"apache-2.0 AND bsd-new" -detected_license_expression=:"apache-2.0 OR gpl-2.0-plus"

It looks like I can reproduce with a simple query like foo" with an unbalanced quote

Added validation in #1210
An error message is now displayed in place of the 500 error.
