restore: print JSON versions of errors in --json mode

Browse source 
Previously, they were printed as freeform text.

This also adds a ui.Terminal interface to make writing
tests easier and also adds a few tests.

Enhancement: Print JSON-formatted errors during `restore --json`
Restic printed any restore errors directly to the console as freeform
text messages, even with `--json`. Restic now prints them as JSON formatted
messages when `--json` is passed.

Bugfix: Include missing backup error text with `--json`
Restic was not actually providing the text of an error message during
backup if `--json` was passed, instead only printing `"error": {}`.
Restic now includes the error text in JSON output.
