It is a fluke because I got this too and have no previously installed beta of Xcode or command-line tools. I do have Xcode 10.2.1 and its corresponding command-line tools installed. This software update is something that Apple will have to address on their end, as we can do nothing about it — except not install it.
I'm seeing the same thing. I filed a bug report for it through Feedback Assistant; they're more likely to see it there than on this forum.
It looks like Apple has resolved the issue; my Mac is no longer showing this update as available:
