Fetch local state before creating it

[Lumene98]

Don't you get failed to fetch app local state during creation because of, for example in manager,

AlgoSwap/contracts/manager.py

Line 49 in ad1959d

read_key_token1 = App.localGet(Int(1), KEY_TOKEN1)

It should fail since the local state hasn't been created yet, how do you prevent it from happening?

if that key does not exist it will return a 0. You could always use localGetEx as well.
