Comment 4 for bug 1692986

Worked for me, thanks Skye.

I've added a signoff branch here: http://git.evergreen-ils.org/?p=working/Evergreen.git;a=shortlog;h=refs/heads/user/cesardv/lp1692986-webstaff_checkout_fails_for_barcodes_with_spaces-signoff

ps: I think Skye's branch name had a typo in the lp# part ("user/showard/lp1629298-web-client ...") thus I corrected that in the signoff branch above.
