Searching for "my:hidden" gives no results because all hidden images are hidden and there is no button to change that

[HushedFox]

Describe the bug
If you want to see all your hidden images you won't see them when searching for my:hidden because if there are no results then the bar with page navigation and "random image" and "show hidden" buttons is not displayed, and the default state is for the hidden images to be hidden.

Only way to access those images is to search for something else, click on "show hidden" so that url changes to include hidden=1& and then edit that url to have q=my:hidden and the end:

https://furbooru.org/search?hidden=1&q=my:hidden

To Reproduce
Steps to reproduce the behavior:

1. Have at least one image set as "hidden"
2. Search for my:hidden - https://furbooru.org/search?q=my:hidden
3. See that there are no results
4. Go to https://furbooru.org/search?hidden=1&q=my:hidden
5. See that there in fact are results

Expected behavior
Searching for my:hidden should show all hidden images by default or at least the button "show hidden" should be available.
