#93 fixed sharing onOptionClick handler in multiple autocomplete instances

[bugy]

This is a bugfix for #93

Proposed changes

As a part of this PR I make autocomplete options independent between instances

Also there is a fix in dropdown.js : _moveDropdown, which avoids adding a component to the same parent twice (it caused tests to fail, since on the second append a child was removed from a parent)
