This PR touches files which potentially affect the outcome of the tests of an exercise. This will cause all students' solutions to affected exercises to be re-tested.

If this PR does not affect the result of the test (or, for example, adds an edge case that is not worth rerunning all tests for), please add the following to the merge-commit message which will stops student's tests from re-running. Please copy-paste to avoid typos.

Edit: resolved in problem-specifications

[senekor]

I struggled with the separation of the name_for and of_rna methods, which is not intended by problem-specifications. I considered to map all tests with only one output amino acid to the name_for method, but that doesn't work because of some edge cases:

• one amino acid and then immediately a stop codon (should test of_rna)
• invalid codons returning None (should test name_for)

So the solution I came up with for now is to add all previous name_for tests as custom tests. This leads to duplicated tests (same input once for name_for and once for of_rna) but preserves the existing exercise design.
