persistent_task should respect the environment

[thofma]

As I learned from @lgoettgens:

The persistent task test does not work with deved dependecies

Would be great if it could work with deved dependencies. I guess this boils down to respecting the environment when spawning the test.

@timholy @NHDaly since you two introduced the test_persistent_tasks test, do you have any idea on how to adapt it to respect deved dependencies (and more general all dependencies that are not just taken from the registry, but via a local path, a git revision etc.)?

[NHDaly]

😬 no, i don't have much of an idea about that. I'm not really clear on why it would be harder, even. Can you share more info?

[timholy]

I'm also unsure what this is about. But looking at the code, I noticed two Pkg-related and one julia-options candidates:

• Aqua.jl/src/utils.jl

  Line 38 in 1fca5d9

  function root_project_toml(pkg::PkgId)

• Aqua.jl/src/persistent_tasks.jl

  Line 81 in 1fca5d9

  prev_project = Base.active_project()::String

• Aqua.jl/src/persistent_tasks.jl

  Line 112 in 1fca5d9

  cmd = `$(Base.julia_cmd()) --project=$wrapperdir -e 'push!(LOAD_PATH, "@stdlib"); using Pkg; Pkg.precompile(; io = devnull)'`

Since I don't know what you're experiencing, this is a blind guess. Perhaps passing more info into precompile_wrapper would fix it?
