Document and test concurrent write requests
BTLE communication is serialised. However the Qt API provides the
ability to issue multiple write requests while the first is still
pending. The backend must enqueue the requests for later on.
This behavior was already indirectly tests by a unit test but this
patch adds an explicit test section for it and documents the behavior.
