Subject: [PATCH] Add Rust clone of python `prepare_and_send' test

Previous version of patch, that changed type of `dc_msg_t.text' to String had
been breaking `prepare_and_send' test in Python.

This commit adds same regression test, reimplemented in Rust, since running
Rust tests is simplier and faster.
