[clang-tidy] Correcting tests for ReplaceRandomShuffleCheck

[koldaniel]

Summary

Usage of the tag "CHECK-MESSAGES" in this test file is incorrect, since it is used as "CHECK-MESSAGE". This does not make the tests fail, but the check for correct warning messages will never happen.

[JonasToth]

Did you grep for that mistake on all test cases?

[aaron.ballman]

One small typo with one of the test changes, but otherwise LGTM, good catch!

test/clang-tidy/modernize-replace-random-shuffle.cpp

51

std::random_shuffle was correct; remove the extra 'd'.

Yes, I did, there were no other occurrences.

Ok. Very nice.
