tmt process even disabled objects

[sopos]

The following plan should rather not find anything than failing on unhashable type: 'DependencyFmfId'

/test:
    enabled: false
    require:
      - name: /library
        type: library
        path: ../tests
    duration: 5m
    test: ./runtest.sh
/plan:
    discover:
      - how: fmf
    execute:
        how: tmt

$ tmt run discover
/var/tmp/tmt/run-049

/plan
    discover
        how: fmf
        directory: /home/dapospis/test/git/SP_components/a

plan failed

The exception was caused by 1 earlier exceptions

Cause number 1:

    unhashable type: 'DependencyFmfId'

I would expect tmt not to process disabled objects.

Hm, leaving the enabled aside, using unhashable types like DependencyFmfId dataclass in set() is a nasty bug...

Trying to fix the error message with #2300

I'm afraid there is no way of not processing disabled objects as processing is the 'fmf' (file format) responsibility and disable/enable comes from tmt (metadata specification).
