test: fix CopyToClipboard tests broken by bad merge conflict resolution

The merge of master into js/removeJQuery incorrectly kept old jsverify
code in the Keyboard shortcut hint tests instead of the fast-check
versions from this branch. Also updates the copy-document DOM fixture
to match the current CopyToClipboard.init() which binds #copyShortcutHintBtn.
