`IndexError: list index out of range` for stored procedures

I get a crash when trying to run a built-in stored procedure:

Sorry about this @ericlathrop, can you provide some more details on your OS and the exact procedure you're attempting to run?

$ uname -a
Linux xps 4.15.0-72-generic #81-Ubuntu SMP Tue Nov 26 12:20:02 UTC 2019 x86_64 x86_64 x86_64 GNU/Linux

I'm trying to run sp_spaceused, or sp_helpdb

$ mssql-cli -v
Version: 0.17.2

I can repro this. Thanks for letting us know! I'll investigate this further.

Looks like our implementation to support multiline statements is what's causing the break (#130).

We use result_set_summary.request_id as index for query messages but there appears to be a mismatch with the number of messages it's expecting. If I override the index with 0 it works for single-line statements but not when multiline is enabled.

We also need to improve testing to catch queries like sp_spaceused.

I need to look at this at a later time since the solution is seemingly non-trivial.
