fix(tm2): make HTTPClient support https

[thehowl]

Gnochess hotfix (already on the gnochess branch, so no need to prioritize this).

There's two users of parseRemoteAddr: makeHTTPDialer and toClientAddrAndParse. The former creates a net.Dialer, and needs to convert the protocol to tcp when it's http/https, while the latter doesn't, and its value is subsequently used to make the HTTP request itself.

This fixes a bug when doing any query/tx with gnokey when using https:

$ gnokey maketx addpkg --gas-wanted 20000000 --gas-fee 1ugnot \
   --pkgpath gno.land/r/demo/chess1 --pkgdir . --broadcast --remote https://my.remote.server:443 testkey
--= Error =--
Data: server at 'http://my.remote.server:443' returned 404 Not Found
