Revert "TT#46791 Fix floating bug with 'Edit' problem on 'Weekdays' page"

The fix here didn't work well because another ngcp-panel issue has been
noticed and reported as TT#50005, the second AJAX request aborts Selenium
test by hiding "Edit" button. The better approach is follow.

This reverts commit a9399b1efd.
