fix(sqllab): wiped out unsaved changes by delayed actions

[justinpark]

SUMMARY

When a user switches to a tab before the slow table list fetch (such like db_exports) completed, it accidentally wiped out the current unsaved changes. This bug makes SQL Lab randomly resets the code to an earlier state.

This commit fixes the bug by updating the queryEditors object directly when the request queryEditor is not active state.
