Pants Tool Export Bug

With pants >=2.18.0rc1 it is not possible to export python tools with:

pants export --resolve=black

It fails with:

[ERROR] 1 Exception encountered:

Engine traceback:
  in `export` goal

ExportError: No resolve named black found in [python].resolves.

With following versions the black export works as expected:

• 2.17.0
• 2.17.1rc1
• 2.17.1rc2
• 2.17.1rc3
