Bug: Shell command preview text is not updated when modifying the command

[Taitava]

I've typed echo "Hello World!" already, but the preview text shows just echo "Hello ", which was a point when I closed and reopened the settings modal for bug demonstration purposes. After that, I completed the sentence.

There's no errors in the console.

I don't know in which version this started, but at least it's happening with 0.21.0.

TODO:

• [x] Fix the bug.
• [x] Add to CHANGELOG.md.
• [x] Find out all affected versions.

The bug was caused by #366, particularly commit e2e0d341aac19d3799b184cfd600e73410627ff0 .

The bug appears in SC versions:

• 0.20.1 (not 0.20.0)
• 0.21.0

The fix is now released.
