Adds a test to check regressions in parser

[rafael]

Desc

• This adds a test to make sure there are output from goyacc is empty when making changes to the parser. This will catch cases where conflicts in the grammar are introduced.
• This PR should break the tests until we merge this: Revert "Support tables that have columns named desc" #4526

The test failed, which means it passed :). Now that I submitted your fix, can you rebase, and we'll verify that it goes green.

Yei! It works
