Avoid crash on duplicate voice names

Avoid crash on duplicate voice names

- In some cases, the list of voices provided by the browser/system contain voices with non-unique names.
- Previously, name collisions were ignored (probably silently) but added strictness when upgrading to typescript added throwing an error.
- The thrown error may be uncaught, apart from top-level error reporters, which went undetected during testing on systems without name collisions.
  - This commit reduces the error to a log entry, effectively masking the error, and consistently selects the first (if any) voice in the list of matches by name.
  - Masking the error may lead to confusion, if the colliding voices are different enough for users to notice.
- Currently assumed to affect macos systems, perhaps due to the system voice settings allowing upgrading the quality of user-preferred voices.
  - Requires testing on a macos system.
- A proper fix requires further work:
  - Introducing testing/development voice name collisions.
  - Detecting voice differences, apart from name; perhaps `voiceURI`.
  - Informing the user of potential collisions; modifying the voice names, voice list indicators, and/or other user interface changes.
  - If differences are detectable, perhaps automatically selecting high-quality voices.
