Improve Dispatch Errors (#878)

* better dispatch errors

* dry_run to use same DispatchError

* fix dry_run_fails; use correct transfer amount

* Hide ModuleError impl and avoid pulling details from metadata unless user needs them

* fix tests

* actually fix the tests (hopefully..)

* Add a couple more DispatchError test cases

* Add a comment about where the error was copied from

* Also expose a way to obtain the raw module error data

* Remove redundant variant prefixes

* explicit lifetime on From<str> for clarity

* fmt
