Download dataset link broken until query is saved

[georgf]

• Start new query
• enter "describe main_summary"
• execute
• try downloading results as csv or excel

Results:

• links point to "/undefined/"

Once i save the query it's working.

I am unable to reproduce this issue in my local dev build and on staging. I can successfully download query results for unsaved queries.

This should be resolved in prod now

Issue is no longer reproducing. Verified as fixed in FF59(win7) in stmo-stage and stmo-prod
