Fix database seeds for development environment

## What does this MR do?

This MR fixes database seeds for development environment and adds CI test for it.

## Why was this MR needed?

Database seeds for development environment are often broken, and we are not able to catch that when someone modified `db/fixtures` and forgets to reseed database.

Closes #22422

See merge request !6475

The previous fix introduced another leak; as it made
Banzai::Filter::SanitizationFiler#customized? always return false, so we
were always appending two elements to
HTML::Pipeline::SanitizationFilter::WHITELIST[:elements]. This growth in
the elements array would slow the sanitization process over time.

This reverts commit 504a3b5e.

Fixed search dropdown labels not displaying

## What does this MR do?

Returns the search controller method after finding the project & group.

## Why was this MR needed?

The search controller was returning early when the search term was empty causing a bug where the dropdown toggles wouldn't show the correct text - instead defaulting to `Any`.

## Screenshots (if relevant)

Fix find file navigation links

## What does this MR do?
Modified the tables in [find file page](https://gitlab.com/ClemMakesApps/gitlab-ce/find_file/master), so that clicking the entire row will go to the file rather than forcing the user to click on the text

## Are there points in the code the reviewer needs to double check?
We should be good

## Why was this MR needed?
Resolve UI inconsistency. Other pages UX indicate that the rows are clickable when highlighted. It is not the case for this page

## Screenshots (if relevant)
