Pull request #802: Replaced test_element_mismatch with a new test_element_match because
Merge in CASA/casa6 from CAS-14328 to master
* commit 'cee5117dcebdf8c6e43e4f43f2aa9488fe5658c8':
Replaced test_element_mismatch with a new test_element_match because the concept of capturing the exception string from the original test got deprecated with numpy 1.26.4. The new test case tests that fetching a column is the same as creating an array from rows that are iterated from an array.
