fix x verified link

[waelhanfi04]

This pull request addresses an issue related to the xLink and xLinkSpinner conditions in the code. The conditions are used to determine when to display a spinner based on the value of the url field in a form.

The issue being addressed is related to the condition checks. In the current code, the conditions are based on the following logic:

xLink: The spinner is not displayed (!spinner) if the url value starts with 'https://x.com/'.
xLinkSpinner: The spinner is displayed (spinner) if the url value starts with 'https://x.com/'.
However, there's a potential problem with this logic. If the url value doesn't exist (is null or undefined), the code may throw an error when trying to access .indexOf('https://x.com/') on a non-existent value.

To address this issue, I have updated the code to include a check for the existence of the url value before performing the .indexOf operation. Here's the updated code:

javascript
Copy code
xLink:
!spinner &&
sendform
.get('url')
?.value?.startsWith('https://x.com/') === true,
xLinkSpinner:
spinner &&
sendform
.get('url')
?.value?.startsWith('https://x.com/') === true,
By adding the check ?.value?.startsWith('https://x.com/') === true, we ensure that the code will only perform the .startsWith operation if the url value is defined and not null. This change should prevent any potential errors related to accessing properties on undefined values.
