Forecast length overwriting in Fedot API

If we would provide InputData with parameter forecast_length in task_params and wouldn't provide the same task to API, Fedot will faшl with exception Metric can not be evaluated because of: Found input variables with inconsistent numbers of samples: [28, 60] (for example). That means that somewhere values from InputData are overwritten by default (I assume). Need to figure out what's wrong and fix this unexpected behaviour
