Extend Russian grammar tests

[yuryleb]

This PR adds test names for all status street names in Russian grammar rules and fixes some detected errors in grammar expressions.

Actually adding tests is infinite work but maybe somebody could review & merge this PR with made changes? All further efforts could be added with newer PRs (I have some plans to check all Russian street names collated by Russian street names validator but in some far away future)?
@1ec5, what do you think, should I update change log with these quite minor fixes (especially for other languages) or not?

Thanks for your patience and for your diligence with these grammar rules. I agree that we can treat this as an ongoing effort and making further improvements in future PRs.

Sure, if you don’t mind.

The speech synthesizers I tried seem to treat guillemets equivalently to quotation marks, so this rule would be fine. On the other hand, if the instruction is presented visually (which this library doesn’t rule out), is it expected that главная аллея «Годы войны» would be presented as главная аллея "Годы войны" instead?

[yuryleb]

Thanks for checking this - IMHO if modern TTSes could handle different quote styles internally (Garmin's old Nuance Vocalizer Automotive doesn't understand guillemets), it's better just to keep original quotes as is.
I added this change and updated the log.

Thanks again!

@yuryleb, would you mind opening separate issues describing what you’re thinking of doing in this space? We might be able to get others to help with test cases as well. Thanks!
