fix(ct): use default hardhat accounts (#2426)

Uses the default configuration for the hardhat network, including the
accounts. We no longer need to use custom accounts (to be honest, I
don't remember why we ever needed that in the first place). Making this
change also fixes the problem where deployment to the hardhat network
would fail because the hardhat accounts did not have a balance.

Fixes #2419
