"make clean" compiles bundle

[Greg Couch]

When doing "make clean" in the mmcif bundle with an error in src/mmcif.pyx, it tries to compile the .pyx file. It should not do that:

Executing: devel clean . exit true
Compiling src/mmcif.pyx because it changed.
[1/1] Cythonizing src/mmcif.pyx

    for m in models:
        m.filename = path

Found the bug and working on a fix. In core/commands/devel.py:_run, we pass in a reference to a bundle builder method but instantiate an object to use as its self parameter. When we instantiate the object, bundle builder expects to run, so it'll be a small refactor to set up a bundle without building it until asked to.

Delayed the call to make_setup_arguments from init to the functions that need setup args e.g. make_wheel, make_editable_wheel; looks fixed but I'm testing a couple builds (once clean, once using devel clean then building).

Should be fixed by ​this patch for both develop and release/v1.5
