feat(#999): Add PHI/UNPHI Steps to jna Integration Test

[volodya-lombrozo]

In this PR I switch jna integration test from the short profile to the full profile.
By doing this, we enable PHI/UNPHI transformations in the test. It slightly slows down the integration test, but ensures qality.

Also, I slightly refactored benchmark.groovy script to switch between integration tests faster.

Closes: #999.
