clang-tidy bugprone-use-after-move (CleverRaven#33557)

* Enable bugprone-use-after-move

Enable this clang-tidy check and deal with associated warnings.

Mostly these were suppressions for things in the tests that are
specifically testing move constructor semantics, but one case was a
genuine latent bug.

* Fix mismatched declaration name

This error seems to have crept into master.
