Referencing non-existing layer in depfile emits no error, but breaks the referencing layer

[janedbal]

Assume following depfile:

deptrac:
  paths:
    - ./src
  layers:
    - name: Domain
      collectors:
        - type: directory
          value: ./src/Domain

    - name: Other
      collectors:
        - type: bool
          must:
            - type: directory
              value: ./src
          must_not:
            - type: layer
              layer: Domain_typo # typo here, should be Domain

Running deptrac with such config causes no failure or warning about reference to non-existing layer. But this clearly break things, because the Other layer is now empty. This can be verified by deptrac debug:layer Other. When the typo is fixed, Other is filled with tokens normally.

Hmm, this is weird, we have a test for this exact situation in both the main branch and the latest release:

• main: https://github.com/qossmic/deptrac/blob/5dd4bbc507fb6b36468c8de889bdd2d586e4a580/tests/Core/Layer/Collector/LayerCollectorTest.php#L66,
• 1.0.2: https://github.com/qossmic/deptrac/blob/a63284ecacf3f7d992a0c35f0ef3e5d3b5d1bf0f/tests/Core/Layer/Collector/LayerCollectorTest.php#L66

Never mind, found it, I will provide a fix shortly.
