catalog/lease: deflake TestLeaseAtLatestVersion

Currently, TestLeaseAtLatestVersion can flake when the initial version
of a descriptor is acquired, which this test is not designed to handle..
To address this, this patch disables the initial version acquisition to
deflake this test.

Fixes: #139386

Release note: None
