Not all bob packages are taken from local channel

Somehow, mamba is not picking up all bob packages from the local conda channel:

    bob.bio.base:                  6.0.1b0-py38h44fe14c_25      local                                            
    bob.bio.face:                  6.0.1b0-py38h4d93ce0_18      local                                            
    bob.bio.video:                 5.0.1b0-py38hd5d7b21_13      local                                            
    bob.extension:                 6.1.2b0-py38h460ab40_32      local                                            
    bob.io.base:                   4.0.1b0-py38h2539f08_35      local                                            
    bob.learn.em:                  3.0.0b0-py38h4769f04_18      http://www.idiap.ch/software/bob/conda/label/beta
    bob.measure:                   5.0.1b0-py38h521d9d0_31      local                                            
    bob.pipelines:                 2.0.1b0-py38hbfafce2_17      http://www.idiap.ch/software/bob/conda/label/beta

I don't know why yet but that is why the nightlies are broken.
