Merge #10824

10824: project_model: print full cargo command if cargo metadata fails to run r=Veykril a=jhgg

well, `Command` implements a sensible `Debug` which *roughly* does what we want to do. Unfortunately it's got a bit of a quote situation,

So it'd output something like `"cargo" "metadata"  "--format-version" "1" "--features" "foo,bar,baz"`. 

Which although is a bit verbose with the quotes, it's at the very least, not entirely incorrect/misleading.

fixes #10797
