test: Change spelling to "TangerineWhistle" and "SpuriousDragon" (#1576)

Spell fork names without space to match execution-specs:
- "Tangerine Whistle" → "TangerineWhistle",
- "Spurious Dragon" → "SpuriousDragon".

This allows us to execute new test suite for these forks in next release
of tests in execution-specs. Also handy for `evmone t8n`.

We decided not to support old spelling as this fork name is old and not
very user-facing.
