Fix overflow sanitizer in copyWithAuthor.

The array index calculation in NBLog.cpp causes a runtime error on
integer overflow sanitized builds.

 runtime error: unsigned integer overflow: 27 + 4294967295 cannot be
 represented in type 'unsigned int'

This restructures the buffer index to avoid the overflow all together.
