when logging LatinIME.onUpdateSelection(), now include the current word and
preceding word.  no escaping of the word is performed; this is temporary
until the output format is cleaned up.

also fix EditingUtils.getWordRangeAtCursor to support supplementary
UTF-16 characters.

This change also undoes the effects of I8694eb9016, which was an initial
effort built on Utils.UsabilityStudyLogs.  Now Utils operates as it did
previously, for backward compatibility, but the ResearchLogger retains
the new log format.

Coordinated with  I274b75c5.
