Insufficient version range normalization

[sounisi5011]

intersect('>=1.2.3', '<=1.2.3') !== '1.2.3'
// return: '>=1.2.3 <=1.2.3'

intersect('>=1.2.3 <=1.2.3') !== '1.2.3'
// return: '>=1.2.3 <=1.2.3'

There is no difference in meaning between >=1.2.3 <=1.2.3 and 1.2.3.
However, the intersect version range is 1.2.3.
It is appropriate to return 1.2.3.
