[bug]: Investigate spurious build failures

[appetrosyan]

cargo build from workspace root works. cargo build from dir does not.

If you edit the code in client or client_cli crates to rely on API exposed by the data_model::transparent_api feature the build will be successful if run from workspace root, but will fail if run from the client or client_cli directory. This indicates that when built from workspace root cargo unifies all features.

Expected behavior is that build should fail in all cases because data_model::transparent_api feature is not enabled by the client or client_cli crates.

This behavior can lead to a silent breakage of builds

To reproduce:

Commit: b185545

1. cargo check: works (not expected)
2. cargo run --bin iroha_client_cli: works (not expected)
3. cargo check --package iroha_client_cli: doesn't work (that's expeced because we really have an error in the code)
