fix(tasks): surface flux errors on pre auth check

[GeorgeMac]

Closes #14449

This change comprises of a few cosmetic changes to the way the create tasks action surfaces errors. Prior to this change, unnecessary wrapping of platform errors caused the frontend to present unhelpful error messages when failures occured compiling the flux script in a preauth check.

This change ensures that platform errors don't get wrapped more than once during a create task action. It also adds a few more tests throughout to capture this behavior.

See new cypress test for an example of a missing org: in the to() function call and how the necessary detailed information is now presented to the user. Prior to this all errors here were presented as a failure to authenticate.

looks good to me! only thing is the linter error. if you don't already have Prettier installed, I think that will take care of JS linting for you so you don't have to think about it.
