Updating molecular-psychiatry, removing month/day

The current style generates reference list entries that resemble:

Brocke B, Lesch K-P, Armbruster D, Moser DA, Müller A, Strobel A et al. Stathmin, a gene regulating neural plasticity, affects fear and anxiety processing in humans. Am J Med Genet B 2010 Jan 5; 153B: 243–51.

The month and date are inserted after the publication year, but this is not allowed by the journal style. Removed month/day from csl to fix this.
