Fixed KdocComments and KdocFormatting

[DrAlexD]

What's done:

• Made refactoring in KdocComments.
• Added fix test for case when there is class description and some properties in class KDoc at the same time.
• Fixed bug in KdocFormatting for case when @property and @constructor basic tags haven't empty line before them.
• Modified fix test for case when there is class description before @property tag.
• Added smoke test for class KDoc. Currently disabled due to Empty lines in class constructor before properties with comments #1889.

Closes #1884

I do not understand how 90% of refactoring work, but basically there are a lot of tests, so I believe in you :)
