fix: Reject input hostname with protocol

This is quick fix.

Do not accept submitted tor address with protocol since it won't work.

The initial clearnet validation can be done with `net.LookupIP`, but
for tor network can't be done with that method. For now, just inform
to remove the http:// or https:// part to the submitter.
