fix(sql lab): replace the output column in the query history table

[diegomedina248]

SUMMARY

The current output column in the Query History table in the SQL Lab currently displays the schema if the query failed.
The resulting UI is a column with "View results" button for successful queries and some seemingly random text if the query failed that lacks the appropriate context.

This PR makes some cosmetic changes that include:

• Removing the schema for failed queries and leaving the field blank
• Renaming the column from "output" to "results"
• Renaming the button for successful queries from "View results" to "View"

TESTING INSTRUCTIONS

1. Open the SQL Lab
