[Bug] Panic during deployment

[KVolodin]

🐛 Bug Report

If you create an application using leo new from the mainnet branch, a .env file will be created which will contain some kind of private key and the name of the network, if you then rebuild leo from the testnet-beta branch and perform a leo deploy , the private key from the mainnet will break the program, with panic

Steps to Reproduce

Code snippet to reproduce

git clone https://github.com/AleoHQ/leo
cd leo
git checkout mainnet
cargo install --path .

mkdir /tmp/examples && cd /tmp/examples
leo new helloword

cd -
git checkout testnet-beta
cargo install --path .

cd -
leo deploy
