cmd cli does not respect '-c' and '-m' cli arguments

When using the -c and -m cli arguments to specify a particular model parameter set or command config at runtime, a bug in pydarm copies the specified files to the report directory but doesn't use them because it can't find them.

LOG_LEVEL=DEBUG PYTHONPATH=~/repos/pydarm pydarm report -o 0315 --no-gds-filters --no-display -c pydarm_cmd_H1_test.yaml 20240315T032747Z

Results in the following output (note the warning messages in particular):
