Fix inconsistent behavior with the back-to-the-main-keyboard key

With this patch, the back-to-the-main-keyboard in the Emoji
palette will be registered as a key-release action instead of
a key-press action, like switch-to-the-emoji-palette in the
main layout. This provides mroe consistent UX when the layout is
switched from the main layout to the Emoji palette then
switched back to the main layout.
