"Manage localhost" doesn't show after navigating to other nets

re: 8f7ab0b

I noticed that if you click another net, that menu item changes back to "localhost"

Don't feel this is particularly high pri for 0.4.0, but wanted to note it down

yeah - its because we don't have a validator status for localnet if we're not on localnet - i'm only changing the link to the manage page if we know the validator's down,

i think i'd like to make the dropdown more complicated, instead of doign this in the menu, but v0.5.0 :)
