Brandy Smith c38aa07cf8 fix(item-sliding): check for side attribute to avoid an undefined value (#29845)
Issue number: resolves #29499

---------

## What is the current behavior?
Using the bundled version of Ionic results in an error `Uncaught (in
promise) Error: "undefined" is not a valid value for [side]. Use "start"
or "end" instead.` with `<ion-item-sliding>`.

Reproduction 1: 
- https://stackblitz.com/edit/stackblitz-starters-mezoy6?file=index.html
- Press the Add (`+`) button several times

It is also reproducible in an Ionic Angular app when installed via npm.

Reproduction 2: 
-
https://stackblitz.com/edit/angular-exwgke?file=src%2Fapp%2Fexample.component.ts
- Press the `Add Items` button several times

## What is the new behavior?
Check for the side attribute to avoid `side` being `undefined`.

## Does this introduce a breaking change?
- [ ] Yes
- [x] No

## Other information

Dev build: `8.6.1-dev.11749562115.1e681558`

use the fix from the CDN.
