Refactored StoreTokenAction

[twocngdagz]

Hi @dcblogdev

When you refactor to use this action, you inadvertently introduce a bug

if ($tenantId) {
    $where = ['tenant_id' => $tenantId];
} elseif ($tenantData !== []) {
    $data = array_merge($data, $tenantData);
    $where = ['tenant_id' => $data['tenant_id']];
} else {
    $where = ['id' => 1];
}

if $tenantId is set, then the $data does not get merged with $tenantData which contains all tenant information.
Therefore tenant name will not be set in the Xero token model. These will happen the first time the authentication redirects back to the app.

Which will throw this error after authentication
