WebUI: Prevent excessive sync requests

Don't sync main data if a request to do so is already in progress.

This prevents piling up of requests and bogging down slow/busy machines, since the current implementation of `/api/v2/sync/maindata` is very computationally intensive, especially with lots of torrents.

Everything gets updated on the next scheduled request anyway (via the timeout mechanism).
