[Test] Avoid use the same token name in different tests (#74280)

The name token1 is used in both testGetServiceAccountCredentials and
testCreateServiceAccountToken. There are times when the two tests are not fully
isolated. This leads to test failure because indexing of the service token
document must be an op_create. This PR fixes the failure by using a different
token name in testGetServiceAccountCredentials.
