Core/Movement: enable item use and spell cast when dismounting

Remove error message and allow spell cast or item use from
mounted state on ground, especially when sitting on
a landed flying mount. Current behavior is that the player
will get the error message "You can't do that while moving"
when trying to cast a spell or pick up an item
while sitting on a flying mount after having landed.
