tests(wasm): add missing filter tags (#13995)

* tests(wasm): fix some eventual assertions

These checks using assert.eventually() could have yielded a false
positive under certain conditions.

* tests(wasm): add missing filter tags

This adds some missing #off and #postgres tags that are used in CI to
filter out certain testing scenarios.

(cherry picked from commit 8f35f67)
