Update tqdm_logger tests to fit novel format_meter output

[trsvchn]

Fixes #1316

Description:

Novel tqdm's format_meter classmethod now uses tqdm initial parameter; by default it is set up to initial=0, but in tqdm_logger.py it overrides defaults to initial=1, that's why now we expect "?" instead of "00:00", since now we need to consider yet another parameter

Check list:

• New tests are added (if a new feature is added)
• New doc strings: description and/or example code are in RST format
• Documentation is updated (if required)

@trsvchn thanks for the PR and the analysis about initial=1! Currently, #1339 was the first PR to fix the same issue and most likely I'll merge it. Please, check our HF list of issues and feel free to pick one you like to tackle. Thanks !
