[RU] Fix negative temperature pronouncing (#2068)

In russian language TTS doesn't handle negative values correctly and
thus does not pronounce word "minus".

In order to fix this problem, temperature value is checked before
response and if it's negative, word “minus” is added at the response
begining.

This fix addressing #1683 and has been ported from #2038.
