balance_sheet ignoring 'trailing=True' (while cash_flow and income_statement do take it into account).

**Describe the bug**
I assume this is a bug rather than a feature request.

It seems that while when adding 'trailing=True' for cash_flow and income_statement at the TTM row, for balance_sheet it pretty much seems to ignore it (and the alternative is to have 2 calls, the second one being balance_sheet with frequency='q' in order to calculate manually the TTM line.
Not sure if this is a bug (ignoring the 'trailing=True') or a feature request, but I think it would be good (if not too hard) to make it consistent with the other reports and 'save' the need for the manual calculation after issuing a second call for the quarterly data.
```
yq = Ticker(ticker)
yq_cashflow = yq.cash_flow(trailing=True)
yq_income = yq.income_statement(trailing=True)
yq_balance = yq.balance_sheet(trailing=True)
```
