Exception Value: Invalid embedded file: macs/CoNWeT_web-browser_1.5.1.wgt

macs/CoNWeT_web-browser_1.5.1.wgt is an outdated MAC that was uploaded in a previous version of WireCloud. Newer versions of WireCloud won't let this version of the MAC to be uploaded.

This ticket is not about making WireCloud support creating packaged mashups using invalid/outdated MACs, but about making WireCloud return an adequate error code / message instead of the internal server error.
