BUG: Use env_trading_calender for open and closes data
BUG: Use env_trading_calender for open and closes data

TradingEnvironment class uses env_trading_calendar for trading days,
but the default trading calendar for open_and_close data, which causes
errors later, because of misalignment of trading days.

The issue can be resolved by using env_trading_calendar for
open_and_closes as well
