Improve repositories tags consistency
Created by: MorrisNein
It is hard to track consistency of tags in repositories. The new test will help developers to maintain this consistency.
Changelist:
- Added test asserting that all operations have informative tags from ones listed in
OperationTypesRepository; - Moved text preprocessing tools from models repository to data operations repository;
- Added new default tags;
- Default tags are now prioritized in reversed way;
- Minor fix of
OptHistoryvisualization.
