Bug with `cugraph` and `MAT.jl`

**Affects:** PythonCall

**Describe the bug**
I tried to do

```julia
using MAT, PythonCall
py_cugraph = pyimport("cugraph");
```

and it errored (see the end of the bug report for the first few lines of the error).

If, instead I try

```julia
using PythonCall
py_cugraph = pyimport("cugraph");
using MAT
```

it works fine (no errors), and I can run commands from `cugraph`. But this cannot work when preparing a package because all `using` commands supersede the `pyimport` commands defined in the `__init()__` routine. g

I am copying below the state of the `Project.toml` and `CondaPkg.toml` that reproduces this error on `Linux`.

Reproduce the two import orders using the Project.toml and CondaPkg.toml states shown in the report, focusing on PythonCall's __init__ routine and pyimport calls. Compare the failing and working initialization paths and the displayed libaws/libarrow stack trace. Done means the documented package-preparation scenario works without the cugraph initialization error.
