Refactor the uri match fix and fix ssh-key sync (#5339)

* Refactor the uri match change

Refactored the uri match fix to also convert numbers within a string to an int.
If it fails it will be null.

* Fix ssh-key sync issues

If any of the mandatory ssh-key json data values are not a string or are an empty string, this will break the mobile clients.
This commit fixes this by checking if any of the values are missing or invalid and converts the json data to `null`.
It will ensure the clients can sync and show the vault.

Fixes #5343
Fixes #5322
