LinearAlgebra tests failing when run directly

[dlfivefifty]

I'm getting failed tests, even though running all the Julia tests at once works fine:

Yeah, because of being available in Main and then #23806 kicks in. This has been tripping up people lately, need to figure out some good solution to it...

[dlfivefifty]

A simple work around would be to have both cases in the tests

[StefanKarpinski]

Also, note that I very sneakily added repr(obj, :module => nothing) (or any other IOContext pairs) to control the context to which obj is shown.
