Save user specified daemon host when using manual install (#245)

At least for manual install, currently, a custom host is not saved as
the front-end overwrites it which is quite confusing.
'host.docker.internal' is not resolvable under a Linux install of docker
by default so it might make sense to not enforce this as a default
setting in any case.
