[BUG] `_validate_intersecting_segments` in `plot_backtest_interactive` plotters and random folds

[martins0n]

🐛 Bug Report

If we use FoldMask and there is intersection between folds plot_backtest_interactive raises error

Expected behavior

It should work like non-iteractive version

How To Reproduce

• duplicate FoldMask for backtest
• use wandb.logger with plot option

Environment

No response

Additional context

File "backtest.py", line 63, in <module>
    metrics, forecast, info = pipeline.backtest(ts=ts, **backtest_configs)

    tslogger.log_backtest_metrics(ts, metrics_df, forecast_df, fold_info_df)
  File "/usr/local/lib/python3.8/site-packages/etna/loggers/base.py", line 147, in log_backtest_metrics
