Fix nile init command small issues

[ericnordelo]

Issue 1: Different spacing between logged lines after running the command:

(env) ➜  first nile init              
🗄  Creating project directory tree
⛵️ Nile project ready! Try running:

nile compile

Issue 2: Creation of a never used accounts.json file (without the network prefix).

Heh i've been fighting that spacing a lot, not easy. Not sure if small issue but i'd remove either the declarations file altogether.
