Fix the validator error tooltip title attrib

[Ben Petersen]

Code snippet when bug found:

<span ng-if="entry.keyValidatorErrorTooltip || keyValidatorErrorTooltip" class="help action-inline">
            <a aria-hidden="true" data-toggle="tooltip" data-placement="top" title="{{entry.keyValidatorErrorTooltip || keyValidatorErrorTooltip}}">
              <i class="{{entry.keyValidatorErrorTooltipIcon || keyValidatorErrorTooltipIcon}}"></i>
            </a>
          </span>

did not render properly via bootstrap tooltip, hack around was to use data-original-title="" directly, but this isn't right.
