[dropdown] Remove Label Errors Under Certain Conditions

[seddonm1]

Hi,
There is an issue on the multiple selection search drop down where you are able to add multiple items from the dropdown but cannot remove them:
Uncaught TypeError: Cannot read property 'split' of undefined

You can reproduce this on the official Semantic-UI site if you go to this link (http://semantic-ui.com/modules/dropdown.html#search-in-menu) look at the second drop down (the "ui multiple dropdown" one) add any item then try to remove it by clicking the cross icon.

I'll patch this asap.

Mixed in the commit with another feature, but remove label was not correctly pulling input value.

Should be fixed in patch today.
