"Show all request types in the widget" option doesn't actually show all request types in the widget

Summary

When you're configuring the project Widget (Project settings > Widget) one of the settings options is to "Show all request types in the widget", which gives us the impression that when we open the widget in the web page its in all the request types will be shown without the need to type anything for them to show up, however when the open the widget it doesn't show all the request types available for the selected project, just the ones that match the seach.

Steps to Reproduce

1. Create a Widget in the project
2. Copy its code and save on an html file
3. Open this html file and type some word and press Enter for the widget to open

Expected Results

When the widget opens all the request types would be shown as the "Show all request types in the widget" setting implies.

Actual Results

Only one or a few request types are shown, not all of them.

Workaround

None.
