Add ktlint rule ID in formatter callback exception

[smpanaro]

When ktlint fails to autocorrect an issue, you get an error:

Step 'ktlint' found problem in 'src/main/java/Main.kt':
Error on line: 337, column: 41
Unexpected whitespace
// stacktrace

This adds the rule to the error:

Step 'ktlint' found problem in 'src/main/java/Main.kt':
Error on line: 337, column: 41
rule: experimental:parameter-list-spacing
Unexpected whitespace
// stacktrace

Happy to merge if you fix broken tests :)

Of course! I also made a small change to put the word rule: in front of the rule.
