JsonWriter requires that its clients pass it only a single top-level object.
The existing implementation tries to make code cleaner by having mJsonWriter
never be null, and instead use a global static "NULL_JSON_WRITER" that just
discards data.  But because JsonWriter complains if more than one top-level
object is passed, making this a global object does not work.  This change
instead copes with mJsonWriter being null.

This is an optimization. It also happens to work around what
seems to be a framework bug in JB MR1 / MR1.1.

Previously, mMainResearchLog and mMainLogBuffer were set up
when the user moved to a new TextView, and set to null when
the user left the TextView.  This change causes
mMainResearchLog, mMainLogBuffer, mFeedbackLog, and
mFeedbackLogBuffer to be non-null forever after init() is
called.  start() no longer sets up these fields; instead
they are cleared and reset every time stop() is called.
Checks for null values are now removed.

The earlier code just didn't initialize these variables if
the user disabled logging, but since the new version
invariantly keeps these variables valid, we add a check for
whether the user has enabled logging in publishLogUnits().

This is a bug; the ResearchLogger uses ResearchSettings.readResearchLoggerEnabledFlag() instead,
which the user cannot change.  (We assume they will just switch to a different keyboard.)

- Don't call finishComposingText when useless.
- Add safeguards against calling setComposingRegion when the
  data returned by the editor is inconsistent.
- Cancel pending recorrection messages when new messages arrive.
