Fix volumes and networks list/prune filters in http api
This is the continuation work started in #9711. It turns out that list/prune commands for volumes in libpod/compat api have very dangerous error handling when broken filter input is supplied. Problem also affects network list/prune in libpod. This commit unifies filter handling across libpod/compat api and adds sanity apiv2 testcases. Signed-off-by: Jakub Guzik <jakubmguzik@gmail.com>
