fix(sql lab): SQL Lab Compile Query Delay

[diegomedina248]

SUMMARY

There's currently a lag when entering a query in the SQL Lab.
If you set some text and immediately submit the query, you'll most likely get the previous stored query executed.
This is specially notorious if you use keyboard shortcuts to fire the query.

This PR removes the sql query stored locally in the component in favor of the one stored in the redux store, to prevent the two states to be out of sync.

Funny, I had never run into this before, but this was a really bad bug. LGTM and tested before and after and change works as expected (I did notice a lot of unrelated rerendering going on when typing stuff in the editor, but that's obviously outside the scope of this PR). Great work!
