    IMPALA-10605: Deflake test_refresh_native
    
    This test uses a regex to parse the output of
    describe database and extract the db properties. The regex assumes that there
    will only be 1 key value pair which is broken when events processor is
    running. The fix is to modify the regex so that it only extracts the
    relevant function name prefix and its value.
    
    Testing:
    1. The test fails when events processor is enabled. After the patch
    the test works as expected.
