Auto merge of rust-lang#13151 - Alexendoo:nextest, r=Jarcho

Fix running compile-test under cargo nextest

`ui_test` itself has `cargo nextest` support which we now use - oli-obk/ui_test#161

It prints `ui_test` as its test name whereas we printed `compile_test`, this ended up being treated as a test name filter causing all the tests to be filtered out
