Fix lucene compat tests by keeping asserts disabled (#136094) (#136111)

These asserts have been enabled for the lucene compat because
`oldVersion` is now correctly set after #134584.
Previously, in the Lucene compatibility tests, version was always
set to `0.0.0` so the asserts were always disabled.

Additionally, re-enable the tests that were muted because of the issue

(cherry picked from commit b1a861e)
