[Storage] Fix Storage tests that use `lease`

[vincenttran-msft]

Some tests that use lease at the moment don't specify a duration, which means the lease never expires. This can be problematic because sometimes local tests being run over and over may not have the lease duration expire in time!

Thanks for the feedback! We are routing this to the appropriate team for follow-up. cc @jalauzon-msft @vincenttran-msft.
