Allow named non-package project

[fredrikekre]

$ cat Project.toml 
name="MyProject"
uuid="81de396f-a148-4a69-b217-b58614fed4bb"

$ jlpkg resolve
PkgError: expected the file `src/MyProject.jl` to exist for package `MyProject` at `/tmp/tmp.N0Z4kqJFBs`

I second this, another use case for me is when I install a CLI project (a package that generates a CLI to .julia/bin) I want to have an isolated project environment generated instead of mutating the package Project.toml that may have no permission for the CLI.

Why do you need it to be "named" for that application?

[Roger-luo]

I think I just copied the package environment then mutate on that? So there's a name in it. Or yeah you are right, I may not need the name but only a deps field.

Would this also allow for Pkg.test() to work without having a src/MyProj.jl?

(Is there an work-around apart from creating a minimal src/MyProj.jl?)

Oh that would be wonderful and would also solve JuliaDynamics/DrWatson.jl#67
