[youtube] misc cleanup and bug fixes (#505) 

* Update some `_extract_response` calls to keep them consistent
* Cleanup continuation extraction related code using new API format
* Improve `_extract_account_syncid` to support multiple parameters
* Generalize `get_text` and related functions into one
* Update `INNERTUBE_CONTEXT_CLIENT_NAME` with integer values
