some tickers gives an error on collect_all_ratios() function.

Execution error

example code is as below:
company = Toolkit(tickers=['DOM.L'], api_key=API_KEY, quarterly=True, sleep_timer=True, benchmark_ticker=None, progress_bar=False, start_date="2000-01-01")
company.ratios.collect_all_ratios()

Solved this issue, it should work in v1.8.5, let me know if it doesn't.
