Fixed LineLength

[DrAlexD]

What's done:

• Fixed bug when fix-result of rule LineLength execution still contained LineLength warnings. To fix this, added loop that trying to fix LineLength rule warnings until warnings run out.
• Added MAX_FIX_NUMBER for limit on fixing to avoid infinite loop. If the limit is reached, then error message is displayed.
• Added unFix() method realization inside FunAndProperty and ValueArgumentList classes to undo incorrect unnecessary fixes.
• Fixed bug for case when long comment followed multiline property initialization.
• Fixed and reworked several fix tests.

It's part of #1737
