method call listener retry bug fix, method call response serializaiton failure fix,

- Added retry logic to the QuickAccess tab fetching in the method call listener.
- Added exception handling, in case a plugin method returns something that can't be serialized as JSON.
- Changed a few log calls from info to debug to prevent spam
- Added a filter for asyncio base_event log records, since they get spamy and don't provide any useful info most of the time. This can be turned off with the LOG_BASE_EVENTS envar.
