fix: pin type filtering in pin.ls

Old version returned indirect pin
when `pin ls -t direct <path>` was executed.

This fixes filtering and adds necessary tests.

It also tweaks error handling to match behavior
from go-ipfs/js-ipfs-http-client and pass interop tests
from ipfs-inactive/interface-js-ipfs-core#375
