Today we ignore a translog file if the rename operation fails. This can be problematic
on windows if another process hodls on to the translog file. If we can't rename it we should
at least try to copy it since otherwise its content will just be lost.
This is a workaround for an already fixed issue in 2.0 since all translog files are write
once in 2.0 and renaming / copying is not needed anymore.
