remove binary locale/en/*messages.mo file, didnt contain english

[mtmail]

When I start the website locally and access it from a browser set to english (en_GB) it prints Russian.

All messages.mo file in www/locale/ are human readable text files. Except the en file which is binary and contains Russian strings.

This PR removes the file.
