Search in Workspace: fix history for programmatically added text

[gbodeen]

What it does

Fixes #10437 .

How to test

1. Open Theia to e.g. the Theia repo. Open the search in workspace widget. Type a few things into the search field, pausing in between to let the search & history update happen. Use the up-and-down arrows to view the contents of the history.
2. Open an editor, select an interesting word in it, and hit ctrl+shift+F to search for it. It will appear in the search input field of the SIW widget. Now use the up-and-down arrows to view the contents of the history, and the programmatically-added search string will be found in the history as it should be.

I can confirm that the issue exists on master and is addressed by these changes nicely 👍 Also, thanks for cleaning up the getElementById calls.

@gbodeen not related to your changes but do you mind adding the following to the replace and glob (include & exclude) inputs:

autoComplete='off'

Currently only the search input has this option off and I discovered the issue for other inputs when testing your changes:

theia/packages/search-in-workspace/src/browser/search-in-workspace-widget.tsx

Line 488 in 2ab4dcc

autoComplete='off'
