fix!: The gateway should not call initialize_tracing

[justinabrahms]

Initializing tracing is the responsibility of a surrounding binary, not library code.

[jsantell]

Aye initialize_tracing should only be called in main functions in executables and test functions; running a gateway (via orb) initializes this here:

noosphere/rust/noosphere-cli/src/native/mod.rs

Line 45 in 5a84d7a

initialize_tracing(None);
