[BUGFIX] Silence regexp pattern errors in EXT:redirects

This change adds a `@` silence operator to the usage of
`preg_match()` in the `RedirectService`. This prevents errors
in case of manually-entered malformed regexp patterns and follows
existing similar usages of the service.

Additionally, a todo comment is added to evaluate future early
pattern evaluation in record creation/editing so that
a proper response to invalid patterns can be emitted.
