solana/agent: always submit signature verify transactions 

The first transaction acquires a pseudo-lock by setting
initial_creation = true, which will fail if a signature account
already exists. However, this is unsafe since the operation
consists of multiple operations and is not atomic - if the first
validator fails to submit a full set of signature transactions,
other guardians will not retry submitting signature verification txs.

We disable this mechanism to never set initial_creation, which
causes guardians to spend more fees in exchange for fault tolerance.

Instead of failing with an AlreadyExists error, duplicate transactions
will now succeed as a no-op and all nodes will attempt to submit
the full series of signature transactions.
