[Test] Require specifying parser for FIR test. Unify names for FIR tests

Now all tests with `Fir` in name are named accordingly to parser which
  is used in them -- `FirPsi` or `FirLightTree`. This is needed to keep
  consistency between different types of tests, because there is no
  single default in parser mode between different scenarios of using FIR
