lupdate: Remove wrong error messagev5.5.0-alpha1

For qsTr(), when string is not literal we printed a warning saying
"text to translate must be a literal string". This was not correct, as
it has never been a requirement for the string to be a _literal_ string.

The solution is to remove the message entirely.
