Parser raises an exception for not supported query type when query starts with a comment
When working on [index-digest's PR](https://github.com/macbre/index-digest/pull/244) I have found the following issue.

An example call:

```python
tables = get_query_tables("/* foo */ INSERT IGNORE INTO `0070_insert_ignore` VALUES (9, '123', '2017-01-01');")
```

Error raised:

```
/* foo */ INSERT IGNORE INTO `0070_insert_ignore` VALUES (9, '123', '2017-01-01');

        if self._query_type == "UNSUPPORTED":
>           raise ValueError("Not supported query type!")
E           ValueError: Not supported query type!

env/lib/python3.9/site-packages/sql_metadata/parser.py:94: ValueError
```

Additionally, we should also log the query itself that caused this exception to be raised.
