Package match spec with both a non equal operator and wildcards fails

Current Behavior

Entering a package match spec with (multiple) wildcards and a non-equal operator fails when trying to install a package. #5021 is related.

Steps to Reproduce

$ conda install "numpy!=*rc*" --dry-run --no-deps

Output:

InvalidVersionSpecError: Invalid version spec: =!=*rc

Expected Behavior

I'd expect the following output:

Solving environment: done

## Package Plan ##

  environment location: /usr/local/var/pyenv/versions/miniconda3-4.3.27

  added / updated specs:
    - numpy


The following packages will be downloaded:

    package                    |            build
    ---------------------------|-----------------
    numpy-1.14.1               |   py36h8a80b8c_1         3.9 MB

The following NEW packages will be INSTALLED:

    numpy: 1.14.1-py36h8a80b8c_1

Especially since $ conda install "numpy==*rc*" --dry-run --no-deps does correctly resolve to numpy-1.7.0rc1.

This still doesn't work as expected, although the behaviour has slightly changed.

Steps to reproduce

First determine the latest version of a package, e.g. numpy (currently 1.21.2 on conda-forge).
Then:

$ conda install "numpy!=*21.2" --dry-run --no-deps

Output:

Collecting package metadata (current_repodata.json): done
Solving environment: done
