fi: fix behaviour of S_2_TO_HEAVY (adding secondary stress)

Browse Source 
Stress flag S_2_TO_HEAVY is currently only used by finnish.

Current behaviour skips adding secondary stress if the following syllable is heavy. The behaviour should be to skip adding secondary stress if the rest of the word (excluding last syllable) contains a heavy syllable.

Source of grammar rule and examples of expected behaviour: http://scripta.kotus.fi/visk/sisallys.php?p=13
