old deps bound are not deleted

[CarloLucibello]

I'm developing a package depending on PythonCall. I changed my CondaPkg.toml file from

channels = ["conda-forge"]

[deps]
h5py = ""
pillow = ">=9.1, <10"
numpy = ">=1.20, <2"
datasets = ">=2.7, <3"
pyarrow = "==6.0.0"

to

channels = ["conda-forge"]

[deps]
datasets = ">=2.11, <3"

I also remove the .CondaPkg folder. Oddly, it seems that the previous bound are still there since during the precompilation I observe

  Updating specs:

   - datasets[version='>=2.11, <3']
   - datasets[version='>=2.7, <3']
   - h5py=*
   - numpy[version='>=1.20, <2']
   - pillow[version='>=9.1, <10']
   - pyarrow==6.0.0
   - conda-forge::python[version='>=3.7,<4',build=*cpython*]
