start_rmote(server_dir) doesn't seem to work with `~/some_path`

Hi,

While trying to get rmote working in an SGE cluster, I tried setting the server_dir argument to a value that would change by day and use a directory that could be accessed through multiple terminal sessions to SGE. So I tried setting server_dir to something like server_dir = paste0('~/rmote/rmote_server_', Sys.Date()) and it initially seemed to work (rmote printed the message with the url) but eventually it wasn't working. That's why I changed my .Rprofile to use /users/my_username/ instead of ~/ and it all worked after that point and now it also prints the To stop the server message. To make the difference in messages clear, I'm posting them here:

Failing with ~/

Serving the directory /users/my_username/rmote/rmote_server_2018_02_16 at http://127.0.0.1:4321

When it works:

Serving the directory /users/my_username/rmote/rmote_server_2018_02_16 at http://127.0.0.1:4321
To stop the server, run servr::daemon_stop("some_number") or restart your R session

I ignore if that's something you would expect or if you meant to have it work with paths that include ~/.

Best,
Leo
