Update to SWR version 2.x (#296)

* Update SWR to version 2.1.5

* Improve generic type names

* Use "isLoading" property of "useSWR" response

* Correctly load library without selected tab

With the latest SWR version the library was empty on the first load.
Not sure what exactly is the reason, but due to "isPaused" the request wasn't sent even after "activeTab" wasn't undefined anymore.
Instead of using "isPaused", passing "null" as the key will also prevent SWR from doing the request.
