l10n server rejects (all?) plural translations

[andy_st]

Log entry:
Translation submission rejected due to message key mismatch after HTML filtering. Original message: stdClass Object ( [one] => Spam (%count) [other] => Spam (%count) ) , filtered message: stdClass Object ( [one] => Spam (%count) [other] => Spam (%count) ) , key: 0a6dadf0f749252492d8d0847d343456, computed key: 0a6dadf0f749252492d8d0847d343456

Not sure why my plural translations got through when testing.
Here, a deep compare of 2 stdclass instances using the === operator fails.

This needs to be changed to do a deep-compare based on the strings.

Fixed in head.
