Handle relative paths when copying project on app add #4532
Description
If I create an app with a local dependency and the following TOML:
name = "SomeApp"
uuid = "6fe06ad9-5ce4-4b58-bb0c-29b0d7e1fd75"
version = "0.1.0"
authors = ["Jakob Nybo Andersen <[email protected]>"]
[deps]
SomeDep = "b5c6e794-171e-4c69-906b-483714562d9a"
[sources]
SomeDep = {path = "../SomeDep"}
[apps.myapp]
And then do ] app add ., it fails with: "ERROR: expected package SomeDep [b5c6e794] to exist at path /home/jakni/.julia/environments/apps/SomeDep".
The issue is that SomeApp's Project.toml is being copied into /home/jakni/.julia/environments/apps/SomeApp, but the relative paths in the Project.toml are not updated to reflect the new location in the file system.
