METRON-2294: [UI] Fixing Stale mode issue in Alert UI Manual Query Mode

[subhashjha35]

Contributor Comments

Problem

Go to
/alert-list
Switch to Manual Query
Switch to Query builder, and switch back to Manual Query
Type something in the timestamp filter textbox.
No StaleMode warning appears.

Cause

In alert-list.component
manualQueryInputEl needs to be undefined to indirectly fire addManualQueryFieldChangeStream() which is responsible to change the staleDataState.
But It's already defined when we switch from the Query Builder to Manual Query mode

Solution

I have removed the condition of manualQueryInputEl being undefined. And it works fine.
