[why] When do group compare, if returned groups of auto_group like below (the dimension number less than 2 for group_key):

groups = { group_key_1 => { dimension_1 => matrix_1 }, group_key_2 => {} }

the group_key will be deleted, then, group compare will have no output.

[how] Reduce dimension number limit from 2 to 1.

[example]

lukaiyi@z9 ~% compare "suite=iperf" -d "os" in z9

[before] <null>

[after]

os_arch=aarch64/os_version=20/pp.iperf.protocol=tcp/pp.iperf.runtime=300/tbox_group=vm-hi1620-2p8g--liangt
