That mod explicitly clears the players inventory after spawn, so not much I can do about that. If it fires after mine, it'll wipe out the portal. You can spawn one in with the console at least, with /c game.player.insert{name="homeworld_portal"} . You may also want to add "portable-electronics" as well, as you're supposed to start with that.
Alternatively it says it's pretty much superseded by new options added to TinyStart, which doesn't look to have that problem.
