TableErrorFormatter: improve formatting of error tips

[FeBe95]

This PR adds some small improvements to the error output, when using the "table" error formatter:

1. Align tip text after 💡 emoji
2. Trim trailing new-line of multi-line tips

Hi, I'd rather remove the extra space after pencil, than have two spaces after 💡 .
