Shouldn't raise an error but a usual logs when an attachment is canceled before upload ended

[StephaneColson]

When an upload of a file is started with OpenPaaS Unified Inbox, not finished, then cancel before it's finished, the following error is raised

Unable to find source-code formatter for language: title james logs. Available languages are: actionscript, html, java, javascript, none, sql, xhtml, xml

This should not be an error but a normal log "An upload has been canceled before the end" or something like that.
