fix: Remove truncation of preprocessor errors

[chrisbreiding]

• Addresses TR-667

User facing changelog

• Cypress now displays the stack from errors thrown in the preprocessor.

Additional details

We used to remove the stack from where there was a preprocessor error. I don't remember why. It may have been that we thought the error was overly verbose when we displayed it. But removing the stack makes it very difficult to debug a preprocessor, so it's better if we keep it and err on the side of it being verbose.

How has the user experience changed?

Users now see the error stack when there's a preprocessor error.

Yeah, this should be helpful. It probably was originally for readability because people see a wall of text in an error message sometimes and go 😵

yeah, you'd think people would be eager to read errors since it usually leads you to a solution, but strangely this is not a universal trait
