[FAB-3403] increase unit test coverage for rwsetutil

This CR - Includes unit tests for covering the corner cases which in turn increases the test coverage for package fabric/core/ledger/kvledger/txmgmt/rwsetutil - Enables debug messages (setting in TestMain) during unit testing - Fixes the package name in the logger to the correct one Change-Id: I84ed2531d0ea8e79622c0dda9e12b934bcb8fb76 Signed-off-by: manish <manish.sethi@gmail.com>
