Some packages not installed editable on coconut

[rikvl]

Trying mkchimeenv on coconut results in some packages being installed editable as expected, while other packages seem to fall back on default system installs.

For example, pip list seems to indicate that ch_pipeline and ch_util are both installed as expected:

(ch) lieshout@coconut:~/test-chime-env$ pip list | grep ch_
ch-pipeline            22.9.0+9.g659a80f      /home/lieshout/test-chime-env/code/ch_pipeline
ch-util                22.9.0+2.gb2abd59      /home/lieshout/test-chime-env/code/ch_util

However, closer inspection shows that ch_util does not use the editable install:

(ch) lieshout@coconut:~/test-chime-env$ pip show ch_pipeline | grep Location
Location: /home/lieshout/test-chime-env/code/ch_pipeline

(ch) lieshout@coconut:~/test-chime-env$ pip show ch_util | grep Location
Location: /home/lieshout/test-chime-env/venv/lib/python3.8/site-packages

(ch) lieshout@coconut:~/test-chime-env$ python -c 'from ch_pipeline import _version; print(_version.__file__)'
/home/lieshout/test-chime-env/code/ch_pipeline/ch_pipeline/_version.py

(ch) lieshout@coconut:~/test-chime-env$ python -c 'from ch_util import _version; print(_version.__file__)'
/usr/local/lib/python3.8/dist-packages/ch_util/_version.py

The packages that seem to be installed as expected are:
ch_pipeline chimedb chimedb-config chimedb-data_index chimedb-dataflag chimedb-dataset
The ones that seem to have problems are:
