Set query arg in economy/eval as required

[elyanah-aco]

Description

Closes #4238 by making the --query arg in economy/eval required. Bug was caused by ns_parser not being NoneType even if no argument was passed. Given that --query has no default value and is dependent on loaded data, it makes sense to require it.
