why remove the PublicSharingDrivers?

[butonic]

because there is no owncloudsql publicshare driver in reva: https://github.com/cs3org/reva/blob/afc8ead0c9a6a0acc5b46bf27a8b18ad458c098d/pkg/publicshare/manager/loader/loader.go#L23-L25

package loader

import (
	// Load core share manager drivers.
	_ "github.com/cs3org/reva/v2/pkg/publicshare/manager/cs3"
	_ "github.com/cs3org/reva/v2/pkg/publicshare/manager/json"
	_ "github.com/cs3org/reva/v2/pkg/publicshare/manager/memory"
	// Add your own here
)
