fix: only call `onClose` when passed via props

[jatinsandilya]

Description

As described our users

So we open the hubspot auth page in a new tab with this code -
revertConnect?.open?.("hubspot")
It does open it in a new tab but then we also receive the error in the screenshot,
We were making an api call after the above mentioned line and it was not getting called due to this error.
For now we are making the api call before executing the open function from Revert as a temporary solution.

We are currently using
"@revertdotdev/revert-react": "^0.0.15",
