Fix SQL generated by updateWithOnConflict()

Before, SQLiteDatabase.updateWithOnConflict() method generated
syntactically invalid SQL if the ConflictAlgorithm was non-null.
For example, it would generate
"UPDATE  OR REPLACEshortcuts SET ...",
when it should be "UPDATE OR REPLACE shortcuts SET ...".
