cql-pytest: remove "xfail" tag from two passing tests
cql-pytest: remove "xfail" tag from two passing tests

Issue #7595 was already fixed last week, in commit
b6fb5ee9128312f5d6a50c815ed5b147f757ccb9, so the two tests which failed
because of this issue no longer fail and their "xfail" tag can be removed.

Refs #7595.
