[RAS] issue fixed: direct login to a specific screen

Hi, A couple of days ago I've started examining the recent error logs from RAS, and I've noticed an issue. Some users loggin in to a direct screen in RAS, like /research/autosuggest (via https://authors.repec.org/research/autosuggest) were getting an "Application error". I've spent some time debugging and found this to be very serious: this error happend to many users. If I understand it right, it primarily happened to those who clicked on the links like the mentioned above in the automatic mails. I still do not know if it happened to all of them or to some. Now I've made a fix and have installed it today. I hope this error does not happen again. I'll keep monitoring and fixing issues. -ivan
