When a wallet account only contains a single UTXO, it is not possible to perform VSP ticket purchasing, because at least two UTXOs are required: one to fund the ticket purchase, and a second to pay the VSP. When UTXO exhaustion is detected during a ticket purchasing attempt with a VSP configured, attempt to split a UTXO into two outputs, followed by a reattempted ticket purchase. The ticket purchase reattempt must be done with a zero minconf policy, since it still uses the normal UTXO selection instead of precisely using the newly created outputs from the extra split transaction. This is not ideal, and may also result in spending other unconfirmed outputs in the account that were not considered earlier during the failed purchase attempt.
