Incorrect partition error message

[mattculler]

Bug Description

Every PartitionUsageError tells the user that the partition names are incorrect, but this exception is used more generally than that.

To Reproduce

Trigger a PartitionUsageError using the part yaml below.

part yaml

parts:
  busybox:
    stage-packages: [busybox-static]
    plugin: nil
    organize:
      "*": (mattos-a)/
    stage:
      - (mattos-a)/
    prime:
      - (mattos-a)/
