reordering ml_commons tests : moved test_search to the end

[rawwar]

Raised another PR as I was unable to sign off a commit in the previous PR.

Fixes #326

Having test_search at the start of the module is making it to run first. Since pytest runs tests by the order they appear in the module. Moving test_search to the end should help to mitigate this issue
