fix(fsharp): load the project when fsautocomplete starts

fsautocomplete waits for the client to load the project through its own
`fsharp/workspaceLoad` request, which the IDE never sent. The server showed as
running, but F# files got no completion or diagnostics. Turning on
`AutomaticWorkspaceInit` makes it load the project itself.
