  --- BEGIN ISSUE ---
  Ticker.history: history's index is not of type DateTimeIndex when dividend and split tables are empty
  **Issue**:
  
  Ticker.history (line 295):
  >       df.index = df.index.tz_localize("UTC").tz_convert(data["chart"]["result"][0]["meta"]["exchangeTimezoneName"])
  E       AttributeError: 'Index' object has no attribute 'tz_localize'
  
  **Reason**: 
  
  During the concatenation of a proper price table with empty dividend and split tables, the price table's index has changed from _pandas.DatetimeIndex_ to _pandas.Index_ because the empty tables had this index type.
  
  **Proposed solution**: 
  
  Modify _parse_actions_ (in utils.py) to initialise the dividend and split tables with : 
  `dividends = _pd.DataFrame(columns=["Dividends"], index=_pd.DatetimeIndex([]))`
   `splits = _pd.DataFrame(columns=["Stock Splits"], index=_pd.DatetimeIndex([]))`
  
  
  Local modules' versions:
  
  finance : 0.1.69
  pandas : 1.4.0
  python : 3.10
