Type ahead with tags is broken

After selecting one of the entries, I'd expect to see a tag. Instead, I see the item as plain text, and there's a cursor below the input field.

It's a weird JavaScript error.

Instead of trying to support the outdated library, we might prefer to switch to one of these alternatives:

• https://github.com/Nodws/bootstrap4-tagsinput
• https://github.com/aehlke/tag-it

The alternative libraries I found above are ill-maintained, too.

The last working version of the library is 0.7.1, so I took it as a basis and implemented the BootsFaces additions. Not it seems to be OK.
