Fix EZP-22085: "Tab" characters in node name error (urlalias_iri)

Link: https://jira.ez.no/browse/EZP-22085

## Description
When having a tab character in a node name, the link to the node was broken. This patch makes the code deal with tabs the way it does with spaces (replace by a separator).

## To fix existing broken nodes
Once the patch applied, editing the node's name will regenerate it or use php bin/php/updateniceurls.php to do bulk node updates.

## Tests
Updated unit test and manual test.
