No exception raised when using send_and_wait and custom instruction

[mattiskoh]

When using a custom instruction based on the RRC custom_instruction template, that sends feedback i.e. parse_feedback, the custom instruction can get stuck and hang forever.

The culprit is the incorrect parsing of the feedback values, that normally would raise a Python Exception. However in conjunction with rrc's send_and_wait no Exception is raised whatsoever.

Expected Result

Python Exception raised

Actual Result

Nothing, script gets stuck.

Reproduction Steps

Parse a feedback incorrectly e.g. string_values[0] when string_values is an empty list

System Information

Operating System name and version, Python version, etc. compas_rrc v 1.1.0

@fleischp let's test this on Friday, I believe this is already fixed in the webservices branch.
