Do not store information for kLicenseTypeTemporary

[ Merge of http://go/wvgerrit/105624 ]

Temporary licenses do not allow for license information to be stored
in any form, whether it is usage information or persisting license
information. Information should not be stored even if can_persist is
set to true and a PST is specified as those are suggestions rather than
a requirement.
