Fixed plurals tests for ICU. Wrong plural classes were used for Russian (2..4 should be other, while 5..9 should be many) - see CLDR 24 release notes http://cldr.unicode.org/index/downloads/cldr-24#TOC-Plural-rule-changes
Removed few plural class from javascript library because of changes in CLDR 24 (ICU4C 52.1).
