Explanation

Ever since commit 8363810485809f0bfd716c930f1dbb1c39df3aa8, when using tagify on IE, we get a js error whenever we get into the "getWhiteListItemByValue" function because it uses the method "find" which isn't supported by IE.

• What is the expected behavior?
  When using whitelists with tagify in IE, I expect to be able to add tags
• What is happening instead?
  I'm getting a JS error
• What error message are you getting?
  “Object doesn't support property or method 'find'”

Thank you for all your hard work, it really is appreciated,
