Rethrow migration exceptions with added information

[In3luki]

[stwlam]

This is already caught at an outer scope

[In3luki]

The current error is something like this:

Error thrown while migrating Actor.L0pXT0ba2Ovsjir9: Cannot read properties of undefined (reading 'flags')

Which isn't very helpful to locate where the error actually occured.

[stwlam]

What additional details does the example screenshot have?

[In3luki]

The MigrationRunner method the error occured in, the Migration version to identify the actual migration that failed and the Migration method the error occured in.

[stwlam]

It's already obvious that a failed actor or item migration is from one of those two methods, and the screenshot doesn't show the migration number.

[stwlam]

Oh, my bad: I see the number!

[In3luki]

Lose everything but the version number, got it. 😄
