STYLE: Remove backslash + indent from literals in tests

Removed unwanted (unintentional) spaces from test output messages, which were
caused by an indentation after a backslash continuation character, inside a
string literal. Using Notepad++ v8.4.5 Regular Expressions:

- Find what: `^([^"\r\n]*"[^"\r\n]* )\\\r\n[ ]+`
- Replace with: `$1`

- Find what: `^([^"\r\n]*"[^"\r\n]*)\\\r\n[ ]+`
- Replace with: `$1 `
