[Fix]: 🐛 Strapi parser middleware, catch block error logging

[ognjenjevremovic]

What does it do?

Throwing error inside of a controller (using plain javascript) results in a different error in parser middleware.
Before calling (String.prototype.includes) method on the message property on the error object, a check should be performed to see if the message property is defined on the error instance so no runtime TypeError is thrown.

Why is it needed?

Throw statements from within the code resulted in a TypeError with stack trace leading to Strapi parser middleware.
Instead, error logging should have appropriate stack trace from within the file where the error is thrown from.

How to test it?

Just in custom controller code, instead of usual ctx.throw(400, "something") write throw "something"

Additional notes?

No new test cases are provided. Even though this is a trivial change (and is just a safeguard from the runtime TypeError), I would be willing to provide new test cases but I would need some assistance of where those should be placed and how can this be thoroughly tested.
