Refactor: use clar2wasm::compile_contract in clar2wasm::compile

[Acaccia]

The Clarinet REPL uses clar2wasm::compile_contract in its routine here.

However, There is a fix for some bug that was introduced in clar2wasm::compile here.
Since it was added here, it is not available in the compile_contract function.

I believe those functions should be refactored so that the fix moves to compile_contract (and every future fixes can be added there) and compile should use compile_contract.
