UITest_calc_tests: disable randomly failing assert for now

make -sr UITest_calc_tests
UITEST_TEST_NAME="tdf53482.tdf53482.test_tdf53482_Range_contains_column_headings_file"

passed for me 10 times in a row without problems after this, while 'make
check' randomly fails here & there since the introduction of this test.
