No longer fail to report content of unfocused text fields in Firefox (#…

…12319)

Fixes #12114

PR #12025 started catching only very specific exceptions when getting selection of edit fields. However in Firefox attempting to get caret for non focused edit fields results in RuntimeError which made it impossible to speak these controls.

Description of how this pull request fixes the issue:
When getting content of edit fields in speech, we're now catching RuntimeError as well and treating this situation like no selection.
