NIFI-2480: Fix for multibyte chars in breadcrumbs
Removed $sanitize from breadcrumbs controller, as it escapes multibyte
chars with numerical reference, and non-English names are not displayed in
human readable way.
Even without $sanitize, html tags can be escaped when Angular binds the
value to text content.
I confirmed that HTML tags are escaped without $sanitize as following
screen-shots:

I hope this can be merged, and it doesn't have any negative impact by
removing $sanitize.
Thanks!
