hg: handle Mercurial RepoError correctly in is_valid_repo_uri

RepoError would be leaked by is_valid_repo_uri.

Now, when for example validating an ssh URL without having the ssh client
binary, it will be shown/logged as:
remote: /bin/sh: ssh: command not found
2020-03-17 17:28:53.907 WARNI [kallithea.model.validators] validation of clone URL 'ssh://no-ssh.com/' failed: Mercurial RepoError: no suitable response from remote hg
and shown in the UI as 'Invalid repository URL'.
