Unify error reporting for launch, refresh and sketch changes

[dmitry-lyfar]

Description

• Make error reporting for refresh, launch and sketch-sdk consistent in cases when the progress is aborted. Earlier, if the change became 'Undone' after Ctrl+C it either reported the results as an aborted change or just finished silently.
• Fix reporting for the sketch-sdk command if sketch refresh was interrupted.

Self-review quick check

• Make decisions that cost a lot to reverse explicit in the PR description.
• Avoid nested conditions.
• Delete dead code and redundant comments.
• Normalise symmetries by sticking to doing identical things identically.

// one way to handle errors
if err := f(); err != nil {
   ...
}

// one way to handle multiple returns
val, err := f()
if err != nil {
   ...
}
...

• Check that coupled code elements, files, and directories are adjacent. For example, test data is stored as close as possible to a test.
• Put variable declaration and initialisation together.
• Divide large expressions into digestable and self-explanatory ones. Use multiple variables if required.
• Put a blank line between two logically different chunks of code.
• Follow the style guide for new error messages.

Docs

• I have checked and added or updated relevant documentation.
• I have checked and added or updated relevant release notes.
• I have included the technical author in the review.

Or:

• I confirm the PR has no implications for documentation.

Looks good, just a style issue
