Bug 34072: Remove float/clear from froms.scss

Bug 34072: Remove float/clear from froms.scss

To test:
- go to /cgi-bin/koha/circ/view_holdsqueue.pl
- inspect something within the page to open the dev tools
- press ctrl-shift-m to show the device toolbar
- use the device toolbar to reduce the resolution of your window
- observe that the search controls are lost at smaller resolutions
- Apply patch, regerate CSS ( https://wiki.koha-community.org/wiki/Working_with_SCSS_in_the_OPAC_and_staff_interface ), clear browser cache
- Try again, you should now see the search controls
- Since this patch changes forms.scss try some other forms in Koha at different screen sizes to make sure they still look correct
