planemo 0.74.3: test fails when run as a tool with a planemo conda dependency

[fubar2]

This is the edge case of planemo being run as a conda dependency in a tool running planemo test being served by planemo.
It arises from galaxyproject/training-material#2428 .
This was working nicely but broke about a week ago.

For a sample planemo_test tool in the examples below, an archive containing the test case archive can be grabbed from test toolshed and unpacked:

wget https://fubar@testtoolshed.g2.bx.psu.edu/repos/fubar/planemo_test/archive/565150681330.tar.gz

A direct test
planemo test .... planemo_test/planemo_test.xml
works and passes.

Running the test manually in planemo with
planemo serve .... planemo_test/planemo_test.xml
and 565150681330.tar.gz uploaded into the history as a toolshed archive, so it can be selected as
the input toolshed archive for the tool,
the tool fails. It does not get as far as running the test.

It's not clear below but there are more explicit tracebacks from generating the tool that show run_tests.sh sees an apparently unrecognised --dev-wheels parameter and prints the run_tests.sh help text. The only place --dev-wheels appears is planemo/galaxy/run.py -

def setup_common_startup_args():
    return _set_variable_if_wheels(
        "COMMON_STARTUP_ARGS", "--dev-wheels"
    )

Traceback from the failed job seen in Galaxy is pasted below.

An error occurred while running the tool planemo_test.

[fubar2]

I can test with a monkey patched run_tests.sh to ignore the current bogus --dev-wheels parameter.
It seems to be leaking into the call to run_tests.sh when it's probably intended for, and a legal parameter for common_startup_functions.sh ? I'll let you know if I can figure it out - you never know.
